Numerical Solution for an Epicycloid Crack

open access: yesJournal of Applied Mathematics, 2014
A flat crack, Ω, is lying in a three-dimensional homogenous isotropic elastic solid subjected to shear loading. A mathematical formulation is developed based on the mixed boundary values for Ω such that the problem of finding the resulting force can be ...
