A rank-one convex, non-polyconvex isotropic function on with compact connected sublevel sets

Jendrik Voss, Ionel-Dumitrel Ghiba, Robert J. Martin +1

According to a 2002 theorem by Cardaliaguet and Tahraoui, an isotropic, compact and connected subset of the group of invertible matrices is ra…

Rank-one convexity vs. ellipticity for isotropic functions

Robert J. Martin, Jendrik Voss, Ionel-Dumitrel Ghiba +1

It is well known that a twice-differentiable real-valued function on the group of invertible ma…

Sharp rank-one convexity conditions in planar isotropic elasticity for the additive volumetric-isochoric split

Jendrik Voss, Ionel-Dumitrel Ghiba, Robert J. Martin +1

We consider the volumetric-isochoric split in planar isotropic hyperelasticity and give a precise analysis of rank-one convexity criteria for this case, showing that the Legendre-H…

Refined dimensional reduction for isotropic elastic Cosserat shells with initial curvature

Mircea Birsan, Ionel-Dumitrel Ghiba, Robert J. Martin +1

Using a geometrically motivated 8-parameter ansatz through the thickness, we reduce a three-dimensional shell-like geometrically nonlinear Cosserat material to a fully two-dimensio…

The axiomatic introduction of arbitrary strain tensors by Hans Richter -- a commented translation of "Strain tensor, strain deviator and stress tensor for finite deformations"

Patrizio Neff, Kai Graban, Eva Schweickert +1

We provide a faithful translation of Hans Richter's important 1949 paper "Verzerrungstensor, Verzerrungsdeviator und Spannungstensor bei endlichen Formänderungen" from its original…

A commented translation of Hans Richter's early work "The isotropic law of elasticity"

Kai Graban, Eva Schweickert, Robert J. Martin +1

We provide a faithful translation of Hans Richter's important 1948 paper "Das isotrope Elastizitätsgesetz" from its original German version into English. Our introduction summarize…
