Elastic Stress Field beneath a Sticking Circular Contact under Tangential Load
Emanuel Willert
Based on a potential theoretical approach, the subsurface stress field is calculated for an elastic-half space, which is subject to normal and uniaxial tangential surface tractions…
Determination of the stress state beneath arbitrary axisymmetric tangential contacts in Hertz-Mindlin approximation based on the superposition of solutions for parabolic contact
Emanuel Willert
As an improvement to the recently proposed procedure for the determination of the stress state beneath axisymmetric tangential contacts in Hertz-Mindlin approximation via an approp…
Short note: Transformation between different solution methods for general axisymmetric tangential contact problems in Hertz-Mindlin approximation
Emanuel Willert
The transition between two conceptionally different solution procedures for general axisymmetric tangential contact problems with arbitrary laoding histories under Hertz-Mindlin as…
The Influence of Compressibility on the Restitution Coefficient for Viscoelastic Spheres in Low-Velocity Normal Impacts
Emanuel Willert, Jean-Emmanuel Leroy, Maciej Satora +1
The influence of compressibility on the coefficient of restitution in the normal impact of a rigid sphere onto a linear-viscoelastic compressible standard solid under quasi-static…
Indentation of concave power law profiles with arbitrary exponents
Valentin L. Popov, Markus Heß, Emanuel Willert +1
We study analytically and numerically the process of indentation of cylindrical rigid indenter with concave face in form of a power-law function. In the well-known case of a parabo…
Detachment of adhesive normal contact between a rigid circular flat punch and a viscoelastic half-space
Emanuel Willert, Valentin L. Popov
We propose an approach to describe the propagation of a crack (or boundary of an adhesive contact) in a viscoelastic material which is only based on the consideration of the rheolo…
