Robust finite element models are utilised for their ability to predict simple complex mechanical behaviour under certain conditions at a very low cost compared experimental studies, as this reduces the need physical prototypes while allowing optimisation of components. In paper, various parameters in techniques were reviewed simulate crushing glass/epoxy tubes with different material models, me...

FINGER iS a Lisp-based system to derive formulas needed in finite element analysis, and to generate FORTRAN code from these formulas. The generated programs can be used with existing, FORTRAN-based finite element analysis packages. This approach aims to replace tedious hand computations that are time consuming and error prone. The design and implementation of FINGER are presented. Techniques fo...

The assessment of the influence of the work-hardening of material on the optimum die profile and drawing force  in rod drawing process is the main objective of the present paper. The upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the rod drawing process through curved dies. Analytical results of drawin...

The Java programming language has several features, which makes it attractive for software development in computational engineering and sciences. One major obstacle to use of Java in computationally intensive applications is its reputation of a slow language in comparison to Fortran or C. In this paper the performance of the developed Java finite element code is compared to that of the C code o...

Abstract In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process has been studied at the room temperature through experimental and finite element simulation method. Magnetic method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various portion of the deep drawn cup under optimum Blank Holder Force (BHF) a...

Thermal buckling behavior of truncated conical liner reinforced by laminated composite is investigated in the presence of a general initial imperfection. For this purpose, the method of virtual work and first-order strain-deformation shell theory are employed to extract equilibrium equations. To this end, a finite element code is developed using the 3D 8-node shell element with six degrees of f...

The objective of this study is to develop robust finite element models of the liver and kidney. The organs are modeled for the first time as hyper viscoelastic materials and with individual constituents of each (viz. the capsule and veins). To characterize the tissues, static and dynamic experiments were performed on individual parts of the porcine abdominal o...

Abstract For the information acquisition of whole motion a projectile with sliding driving band in gun bore, nonlinear dynamic explicit finite element software LS-DYNA was used. The pressure-time curve bore is equivalent to boundary input condition gun, and large deformation process described by ALE algorithm. simulation results show that number calculated data are good agreement experimental v...
