The automotive industry has increased significantly the use of advanced high strength steels (AHSS) in many structural components, with the aim to reduce weight and also to increase safety. The high resistance of these steels is accompanied by a decrease in formability, which makes simulation a requirement to adequately foresee the formability of a particular stretch formed component. This work...

In this study coefficients of the multi-parameter Williams power series expansion for stress field in vicinity central crack rectangular plate and semi-circular notched disk under bending are obtained by use finite element analysis. SIMULIA Abaqus, analysis software, numerical solutions these two cracked geometries found. The with has geometry similar to used digital photoelasticity. Numerical ...

This paper presents the results of an analytical investigation conducted to replicate experimentally obtained behavior, and better understand the behavior of the proposed structural fuse concept for bridges that is presented in a companion paper. First, a steel plate shear link (SPSL) proposed as a new type of structural fuse is described. Equations are derived to define its shear-moment intera...

In this study, a practical seismic retrofit method for RC frames was proposed. For purpose, quasi-static loading applied to 8 different type of in finite elements analysis software, Abaqus and were pushed 45mm laterally. High strength fiber reinforced lightweight concrete panels used strengthen infill walls inside the frames. To apply them walls, epoxy binder polyurethane their behaviour compar...

Multi-site damage (MSD) has been a challenge to aircraft, civil and power plant structures. In real life components are subjected to cracking at many vulnerable locations such as the bolt holes. However, we do not consider for the presence of multiple cracks. Unlike components with a single crack, these components are difficult to predict. When two cracks approach one another, their stress fiel...

The aim of this paper is to carry out extensive numerical investigations about the effect of various parameters on both buckling loads and ultimate behavior of continuous partially composite castellated beams under vertical loads. Efficient nonlinear 3D Finite Element Model using ABAQUS software is developed. The initial geometric imperfection and material nonlinearities were carefully consider...

Abstract: This paper builds upon previous studies (Farrugia, 2006, 2008) for developing a more physical approach to predict the mechanisms of high temperature ductile damage acting at surface/sub-surface and across the length scale of continuously cast free cutting steel billet feedstock. A methodology combining mechanical testing and modelling has been developed to account for local microstruc...

Commercial finite element software follow cautiously the numerical methods developed by scientific community. Even though phase-field method is not a default option in Abaqus, code proposes unique way to implement and test complex, extraneous models. In last five years, fracture models Abaqus have gained unbelievable popularity among scientists engineers alike. However, most implementations are...

Up to now a large number of models have been developed to measure or predict the damage in equipments. Some of these models have been implemented in ABAQUS software. To implement damage parameters in the software, it is necessary to perform complex and expensive practical tests. One of these damage models is Forming Limit Diagram (FLD).The purpose of this research is deriving required parameter...
