International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 13, Page 5185-5212, September 2026.ABSTRACT This study proposes a novel geometrically regularized gradient‐damage model for simulating dynamic mixed‐mode fracture in orthotropic materials with tension–compression asymmetry. In this model, a thermodynamic framework is formulated by incorporating damage dissipation into internal energy evolution, from which the constitutive relation and ...

Macroscopic Coulomb Force Versus Maxwell Stress Theory: Consistencies and Discrepancies
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 9, September 2026.ABSTRACT In macroscopic electrostatics, there are two rivaling concepts describing the electrostatic action of force: the continuous formulation of the Coulomb force and the Maxwell stress theory. Although their mutual consistency is well‐known for free charges distributed continuously on volumes and surfaces, a revisit of the seemingly uncontroversial
