Paper explores some aspects of 3D modeling of ‘aircraft cable’ as mostly used sling wire rope. First, the 1×19 stainless steel core of ‘aircraft cable’ was investigated. The analysis was carried out by finite element method based computer program. The software used allowed two different types of contacts, including friction. The sling wire rope core was subjected to two different types of axial loading. The obtained results were compared with the solutions calculated from the literature (Costello 2012). Finally, using the advanced modeling techniques, the parametric 3D model of 7×19 ‘aircraft cable’ was analyzed using finite element method, in order to provide a better understanding and, hence, prediction, of the mechanical behavior of the sling wire ropes in lifting processes.

Finite element method can provide valuable results and information to evaluate and assess the mechanical behavior of tissue engineered scaffolds. In this investigation, a structurally and analytically based model is applied to analyze and to describe the mechanical properties of wire rope yarns as scaffold or other applications in textile engineering. In order to modeling the mechanical behavior of single yarn, non-linear hyperfoam model with three strain energy potential has been used. The results of finite element model are compared with an experimental approach and showed good agreement between software and experimental analysis with a maximum error at break of about 4.3%. As a result, validation of the finite element method is guaranteed for analysis of other structure of multi twisted yarn or wire ropes.

Contact problem, which exists widely in mechanical engineering, civil engineering, manufacturing engineering, etc., is an extremely complicated nonlinear problem. It is usually solved by the finite element method. Unlike with the traditional finite element method, it is necessary to set up contact elements for the contact analysis. In the different types of contact elements, the Goodman joint elements, which cover the surface of contacted bodies with zero thickness, are widely used. However, there are some debates on the characteristics of the attached elements of the Goodman joint elements. For that this paper studies the type, matching, and meshing of the attached elements. The results from this paper would be helpful for the finite element contact analysis.

Basic concept of structural design is to transmit the loading from superstructure to substructure. This idea normally required sound knowledge of structural design and rational engineering judgments. Recently, there have several techniques that can be utilized to determine the superstructure loading, such as finite element method and tributary area method. However, the compatibility of both methods in order to determine the loading from superstructure is prime important and has been investigated in this research framework. Axial loading, represented as products from dead load and service load, which are imposed on the top of slab is directly transmit to the column nearby and modelled through computer simulation. Models of slab were then varies and studies through comparison with broad dimensions of slab thickness, ranging in 100 mm to 600 mm. Results has shown the increasing of slab thickness will indirectly increases the rigidity characteristic of slab and potential to distribute the axial load equally for all column members. Axial load against slab thickness on corner, edge, center, outer and inner column demonstrated the incompatibility for both methods, finite element method and tributary area method in determining the axial loading from superstructure.

This research mainly concentrates on ultimate strength and buckling behaviour of cold formed steel (CFS) laterally un-braced longitudinally stiffened box sections under flexure. A total of five various stiffener combinations for box sections has been studied by modifying the shape of a simple end stiffened section by the provision of intermediate stiffeners along web, flange or both along web and flange. The influence of different types of stiffeners with respect to various aspect radio’s (H/T, B/T, C/T and H/B) have been studied using Finite Element Method (FEM), and recommendations have been proposed on provisions of different stiffener’s combinations. This study mainly details with ultimate strength and buckling behaviour of CFS laterally unbraced stiffened box sections made by C sections connected face to face.

It is well known that the stent design plays an important role in the outcome of the stenting interventional procedure. Thus, analyzing and comparing the behavior of different types of stent is essential to select the most appropriate stent design to use. Furthermore, assessing the behavior of stent is one of the components of the process in which new biomedical stent devices are designed and approved. Indeed, new stent designs have to be proved to be equivalent to an approved stent to be confirmed from the regulatory agencies. This sets the stage for a series of “stent versus stent” randomized trials designed to show that each newer stent design was not inferior to the prior approved stent. In this paper, finite element method is used to assess the behavior of stents. The objective of this work is to present a numerical alternative for “stent versus stent” complicated clinical studies. Three commercially available stents (the Palmaz–Schatz, Multi–Link and NIR stents) are modeled and their behaviors are compared. According to the findings, the possibility of restenosis is lower for Multi–Link and NIR stents in comparison with Palmaz–Schatz stent which is in good agreement with clinical results.

Wire ropes that have a wide range of applications endure loads, stresses, strains, and moments while carrying out the duty of carrying loads. Wire ropes and strands are frequently used as load carrying elements due to their flexible structure and being reliable products. A prestressing steel strand is a form of the pattern of 1×6 helical wires which supply extra stiffness. Contact conditions between adjacent wires, helical geometry of wires at outer layers make it difficult to find the mechanic response of wire ropes or strands under axial load. A good way to overcome this difficulty is to perform a computer-aided simulation with finite element method. In this study, a prestressing strand having 11.11 mm diameter is computer-aided modeled by using SolidWorks, and then ANSYS Workbench is used to determine the mechanical response of the investigated rope strand. The findings indicate that results remained in the elastic region in all finite element simulations until the strain value of 0.00728. Keywords: prestressing strand, finite element method, tensile stress, strain, twisting moment.
