The aim of this paper is to analyze the use of Finite Element Analysis (FEA) in the teaching-learning strategy of metal forming processes. To this end, students are proposed to use the commercial package DEFORM-3D® for the development of their bachelor and master theses within the research line on incremental sheet forming processes. The student acquires skills and competencies on numerical simulation and design of real metal forming processes valuable for their future professional practice, while strengthening the foundations of these manufacturing technologies. This proposal is consistent with the active teaching methodologies included in the guidelines of the European Higher Education Area (EHEA).

Forging process is one of the most basic metal forming processes. In this study a new forging process is applied to fabricate a precision forging product uniting parking and driven gears in order to obtain lightweight and cost effectiveness of an automobile. Since the united product using the precision forging process needs high quality and new manufacturing process, 3D computer simulation by FEM has been used to reduce some trial and errors in experiment and obtain the deformation, strain, stress and load of the workpiece and die. The study has tried to find out an optimal process including preform design putting emphasis on tooth filling by DEFORM-3D, a 3-dimensional rigid-plastic finite element code.

ResumoO termo ensino e aprendizagem valoriza a interdependência dos processos de ensinar e de aprender. As metodologias ativas de ensino e a teoria da aprendizagem significativa de Ausubel dão protagonismo ao estudante em seu desenvolvimento cognitivo, respeitando os saberes prévios, teóricos e práticos. O objetivo da pesquisa é analisar uma prática educativa, segundo a teoria da aprendizagem significativa, sobre metodologias ativas no ensino em saúde, realizada no Programa de Pós-graduação em Ensino em Saúde, mestrado profissional, da Universidade Estadual de Mato Grosso do Sul. A prática educativa foi realizada em quatro momentos: construção de uma colcha de retalhos pelos participantes; problematização sobre metodologia ativa; construção de mapa conceitual; e apresentação da teoria da aprendizagem significativa por meio de um cordel elaborado pelo grupo. A confecção da colcha de retalhos resgatou os saberes, bem como propiciou troca de experiências e de reflexões. A problematização desencadeou um consenso de que as metodologias de ensino devem ser estrategicamente planejadas, considerando o contexto e os atores envolvidos. O mapa conceitual como estratégia educativa e de avaliação formativa evidenciou que os mestrandos desenvolveram a aprendizagem significativa na temática abordada. A entoação do cordel sobre a teoria da aprendizagem significativa despertou o interesse e a atenção dos educandos. A prática educativa mobilizou subsunçores na temática, com problematização, reflexão e ressignificação, tanto nos participantes quanto nos mediadores, de forma horizontal no ensino e aprendizagem, em que quem ensina aprende, e quem aprende também ensina. Portanto, foi um processo de metodologia ativa de ensino com aprendizagem significativa. Palavras-chave: Educação em Saúde. Metodologias Ativas de Ensino e Aprendizagem. Problematização. Mapas Conceituais.AbstractThe term teaching-learning values the teaching and learning interdependence processes. The active teaching methodologies and Ausubel's theory of meaningful learning provide the student with a leading role in his or her cognitive development, respecting previous, theoretical and practical knowledge. The objective of this research is to analyze an educational practice, according to the theory of meaningful learning, about active methodologies in health education, held in the professional master degree level at University of Mato Grosso do Sul in Health Education Postgraduate Program. The educational practice was performed in 4 moments: a quilt construction by the participants; questioning about active methodology; concept map construction; and presentation of the theory of meaningful learning through a cordel elaborated by the group. The making of the quilt rescued the knowledge as well as provided exchange of experiences and considerations. The questioning triggered a consensus that teaching methodologies should be strategically planned, considering the context and the actors involved. The concept map as an educational strategy and formative evaluation showed that the master degree students developed significant learning in the thematic approach. The cordel intonation about the theory of meaningful learning aroused the students’ interest and attention. The educational practice mobilized subsumers, with problematization, reflection and resignification, both in the participants and the mediators, horizontally in teaching-learning, where those who teach learn, and those who learn also teach. Therefore, it was a process of active teaching methodology with significant learning. Keywords: Health Education. Active Teaching-Learning Methodologies. Problematization. Concept Maps.

The system of relationships and emotions that develop in the teaching-learning process define the complexity of teachers' education and pose the challenge of bringing out the emotional and affective culture that guides school life. Several studies on teaching practices highlight the tendency to refer to technical aspectsas a key dimension of professionalism, rather than on relational and emotional dimensions that can promote the relationship with student. The creative and unprecedented reconfiguration of professional practice is configured as the outcome of a reflexive process of subjective construction and de-construction of the profession and its development.The paper proposes a reflective training experience, which involved 76 teachers, focused on emotional and relational dimensions on teaching and based on the use of the narrative-autobiographical instruments (diary, narrative, metaphor). The results achieved in the monitoring phase show that the training offered an opportunity to reflect on oneself and one's personal and professional experience, starting from the use of alternative perspectives and interpretations than those that are already in use

ABSTRACT Objective: To present the experience of elaboration and implementation of the Active Teaching Model to Promote Critical Thinking (MEAPC), associated to Problem-Based Learning (PBL), for undergraduate students in Nursing. Method: Case report on the experience of the educational intervention (MEAPC + PBL) with undergraduate students in Nursing, in a 20-hour course on Basic Life Support (BLS). The MEAPC was validated by judges to guide the analysis of clinical cases. Critical Thinking (CT) skills were assessed using the California Critical Thinking Skills Test. Result: The educational intervention took place in two phases: elaboration and implementation, allowing not only the production of knowledge about BLS, but also the development of CT and exchange of experiences for teaching-learning. Conclusion: The association of the MEAPC to the PBL in the course of BLS organized the learning, gave opportunity to acquire knowledge and to stimulate the skills of the CT.

The paper is based on the newest hollow railway axle, which utilizes the Pro/E designed multi-wedge cross wedge rolling (MCWR) model, utilizes the finite element analysis software DEFORM-3D to complete the numerical simulation about the whole stage of the hollow railway axle forming process, and analyzes the strain rule at the broadening stage of the hollow railway axle, especially conducts a detailed research on forming character into the strain rule at the multi-wedge transition stage, and finally gets the strain forming mechanism of the hollow railway axle at the broadening stage. The result of the research on the strain rule poses great scientific significance on enhancing the product quality and the production efficiency of the hollow railway axle, and improving the theory of multi-wedge cross wedge rolling.

This paper used finite element analysis of metal forming to study the forging process and die design of aluminum alloy brake parts. According to the process parameters and die design, the brake parts were forged by experiment. First, the die design is based on the product size and considering parting line, draft angle, forging tolerance, shrinkage and scrap. Secondly, the finite element analysis of metal forming is used to simulate the forging process of aluminum alloy brake parts. Finally, the aluminum alloy brake levers with dimensional accuracy and surface hardness were forged.
