Abstract

This study aims to present a finite element modelling and analysis of hyperelastic human muscle laceration by using a continuum mechanics approach under Mode I loading conditions. Two – dimensional model of the muscle was developed according to the dimensions that have been used in past research. The finite element analysis and construction of the model are done in Mechanical APDL (ANSYS) v14.0 software. The research was conducted mainly based on two conditions, which are according to various lacerations length and different loading force. To evaluate the fracture toughness of the human muscle thigh segment, this research has employed finite element method to predict the strain energy release rate by using three-point bending test. Various loading forces in the range of 500 N to 4000 N were applied in an attempt to study their effect on the strain energy release rate (J – integral) and von Mises stress. The results show that the strain energy release rate (J-integral) and von Mises stress increased as the laceration length been increased. It can be seen clearly that both trend of the graphs shown a nonlinear increment. By knowing the value of J – integral and von Mises stress, it will help the designer to create a more reliable and advanced prosthetic and orthotic devices. It can also provide a better view on the design of surgical intervention tools.
