Modelling large-deformation plasticity in metals with edge based smoothed finite element method

The problem of modelling plasticity in materials has been investigated for the past 200 years. Standard theories on yielding for metals go back to the era of Tresca(1864) and von Mises(1913). The rapid rise of the finite element method and new testing techniques in the last few decades led to further research. This thesis aims to model large...

Finite Element Model For Interfaces In Compatibilized Polymer Blends: A Comparative Study on the Mixed-Mode Response of Cohesive Zone Models Implemented With Small and Large Displacement Assumptions

Designing and modeling compatibilized polymer blends require accurate interface model. In addition, it is possible that crazing occurs during failure of the interfaces leading to large deformation prior to complete failure and therefore must be accounted for by the interface model.<br/><br/>A preliminary literature review showed that existing...
