Abstracts : Modified virtual internal bond method with an integration of atomistic scale and continuum scale. In this method the domain is presumed to be consisting of material points which are randomly distributed and connected through virtual bond the stress-strain response is controlled through defined potential function. In this paper an attempt is made to derive the stress and strain expression within the frame work of hyper elastic model by using energy stored in normal and shear bond thus the obtain stress and strain expression are used to write Vu-mat subroutines provided in Abaqus environment. In order to prove the robustness of the code several standard cases of fracture problems are solved the obtained results in respect of crack propagation reasonable agreed with a published literature thus existing modified virtual internal bond method can be used as a fracture studies where complex loading.
