Stress Asymmetry in Hard Magnetic Soft Materials
H. Gökçen Güner, Francois Barthelat, John D. Clayton +3
Hard magnetic soft materials -- soft polymers embedded with hard magnetic particles -- are modeled using continuum magnetomechanical formulations in which the deformation and the m…
A Lavrentiev phenomenon in the neo-Hookean model
Marco Barchiesi, Duvan Henao, Carlos Mora-Corral +1
We exhibit a Lavrentiev gap phenomenon for the neo-Hookean energy in three-dimensional nonlinear elasticity. More precisely, we construct boundary data for which the infimum of the…
Crack Face Contact Modeling is Essential to Predict Crack-Parallel Stresses
Maryam Hakimzadeh, Noel Walkington, Carlos Mora-Corral +2
Phase-field fracture models provide a powerful approach to modeling fracture, potentially enabling the unguided prediction of crack growth in complex patterns. To ensure that only…
Invertibility of Sobolev maps through approximate invertibility at the boundary and tangential polyconvexity
Carlos Mora-Corral, David Mur-Callizo
We work in a class of Sobolev maps, with , from a bounded open set to that do not exhibit cavitation and whose trace…
Phase-Field Modeling of Fracture under Compression and Confinement in Anisotropic Geomaterials
Maryam Hakimzadeh, Carlos Mora-Corral, Noel Walkington +2
Strongly anisotropic geomaterials undergo fracture under compressive loading. This paper applies a phase-field fracture model to study this fracture process. While phase-field frac…
