Finite element simulation of fracture behaviour of nanoglass

Abstract

In this study our main is to understand how differently the nanoglass behaves under mixed mode loading condition, firstly if we change in Notch radius with keeping average grain size constant and secondly change in average grain size with keeping Notch size constant. We performed simulation under condition of 2D plane strain, small scale yielding (SSY) using Anand-Su model. It is observed that the As Radius of notch to average grain size ratio is increasing the volume fraction in yielding is decreasing in case of Effect of Notch size and almost remains constant in case of Effect of Grain size, shear band pattern is diffused in the Nanoglass.
