Finite Element Analysis of a Dynamic Linear Crack Problem

This work investigates the problem of a linear crack in the middle of a uniform elastic medium under normal tension-compression loading. The direct Finite Element numerical procedure is used to solve the fractured media deformation problem, which also includes an examination of the dynamic field variables of the problem. A Finite Element algorithm that satisfies the unilateral Signorini contact constraint is also described for solving the crack faces' contact interaction, as well as how this affects the qualitative and quantitative numerical results while calculating the dynamic fracture parameter.
