Numerical Simulation for Open-Hole Tensile Failure of Lamina-Based and Fabric-Based CFRP Laminates with Explicit Dynamic Finite Element Method

This research represents a design and analysis of Automatic loading copper wire machine for the actuator arm (ALCM). The process of copper wire placement on a single actuator arm type compensates human workers. In this research, copper wire placement set is made as a 3D model by computer program before undergoes arrangement analysis via explicit dynamic finite element method to study a suitable speed for copper wire placing. It is considered by characteristics of copper wire after placed and failures occurred during the process that will define suitable speed of motor rotation. The suitable speed is corresponding to copper wire characteristic as preferred, prevent copper wire fracture and time reduction compare to human work.

Element Method

A simplified implementation of the conventional extended finite element method (XFEM) for dynamic fracture in thin shells is presented. Though this implementation uses the same linear combination of the conventional XFEM, it allows for considerable simplifications of the discontinuous displacement and velocity fields in shell finite elements. The proposed method is implemented for the discrete Kirchhoff triangular (DKT) shell element, which is one of the most popular shell elements in engineering analysis. Numerical examples for dynamic failure of shells under impulsive loads including implosion and explosion are presented to demonstrate the effectiveness and robustness of the method.

Element Method

Thermoforming of cut sheets is extensively used in the industry for various commercial applications. In this process, the sheet is heated to a softened state and subsequently deformed into the mould due to an applied pressure, a vacuum, a moving plug or a combination of these media. The thermoforming-process market is expanding to complex geometries and to a list of potential materials. In this work, I use a no isothermal hybrid approach which combines the dynamic finite element method and the thermodynamic law of perfect gases to study the effect of the temperature of the air flow on the blowing of a thin, isotropic and incompressible thermoplastic membrane. The viscoelastic behaviour of the K-BKZ model is considered. The Lagrangian formulation together with the assumption of the membrane shell theory is used. The numerical validation is performed by comparing the obtained results with the theoretical results for the HDPE grade. Moreover, the effect of the temperature on the thickness and stresses distribution is presented.
