Journal ArticleDOI
A mathematical analysis for indentation tests of articular cartilage.
TL;DR: Solutions for the indentation of the layer by the plane end of a rigid circular cylinder and by a rigid sphere are suggested as useful for the determination of the elastic shear modulus of intact cartilage.
Journal ArticleDOI
A numerical method for solving rough contact problems based on the multi-level multi-summation and conjugate gradient techniques
I. A. Polonsky,Leon M. Keer +1 more
TL;DR: An alternative numerical method for solving contact problems for real rough surfaces using a single-loop iteration scheme based on the conjugate gradient method, which converges for arbitrary rough surfaces.
Journal ArticleDOI
Solution of Crack Problems: The Distributed Dislocation Technique
TL;DR: In this paper, the authors introduce the concept of Dislocation Influence Functions for Plane and Ring Dipole Influence Functions (DIF) and derive the solution of Axi-Symmetric Crack Problems.
