In abdominal aortic aneurysm (AAA), the rupture of the aortic tissue is directly related to wall stress. Thus, the investigation of maximum wall stress is a necessary procedure to predict the aortic rupture in AAA. In this study, computational simulation...

Recent experimental studies showed that shear band development starts at the beginning of triaxial tests. In experimental testing, it is impossible to obtain a soil sample with a homogeneous void ratio. Therefore, a homogeneous deformation, i.e., an elem...

During Civil Engineering works, it is a common practice to upgrade mechanical performances of in situ soils by adding few percent of hydraulic binders such as lime and/or cement. But the specificity of stress state in railways structures (biaxial tension...
