Rate-independent systems

A Mielke, T Roubíček - Applied Mathematical Sciences, 2015 - Springer
Our work on rate-independent systems was stimulated by our search for evolutionary
material models for shape-memory alloys that are flexible enough to encompass nonlinear …

A mixed-mode phase field fracture model in anisotropic rocks with consistent kinematics

EC Bryant, WC Sun - Computer Methods in Applied Mechanics and …, 2018 - Elsevier
Under a pure tensile loading, cracks in brittle, isotropic, and homogeneous materials often
propagate such that pure mode I kinematics are maintained at the crack tip. However …

BV solutions and viscosity approximations of rate-independent systems∗

A Mielke, R Rossi, G Savaré - ESAIM: Control, Optimisation and …, 2012 - cambridge.org
In the nonconvex case, solutions of rate-independent systems may develop jumps as a
function of time. To model such jumps, we adopt the philosophy that rate-independence …

Damage and fracture evolution in brittle materials by shape optimization methods

G Allaire, F Jouve, N Van Goethem - Journal of Computational Physics, 2011 - Elsevier
