Mechanical tests of a ferritic-pearlitic steel were conducted at −196 °C with various specimen geometries resulting in different stress states. Elastic-plastic finite element method (FEM) simulations were used to analyze the local stress and strai

Sandia National Laboratories have carried out the Sandia Fracture Challenge in order to evaluate ductile damage mechanics models under conditions which are similar to those in the industrial practice. In this challenge, the prediction of load-deforma

In this paper, a damage mechanics based failure criterion for seismic resistant structures is presented. The utilised innovative damage model serves to predict ductile material failure in terms of crack initiation and is suitable for cyclic high stra

The structural application of HSLA steels can be fostered by considering their ductile failure properties in design. To achieve this we discuss an approach to numerically derive Johnson–Cooks criterion from GTN simulations. The critical state is as

Ductile failure of structural metals is relevant to a wide range of engineering scenarios. Computational methods are employed to anticipate the critical conditions of failure, yet they sometimes provide inaccurate and misleading predictions. Challeng
