Closed-Form Critical-State Caputo Flow for a Teardrop Bounding Surface: Operator Semantics and Factorial Consequences

Closed-form Caputo gradients in critical-state stress-fractional plasticity have relied on the polynomial Modified Cam-Clay surface. We extend them to the non-polynomial teardrop bounding surface by defining the operator as a Caputo derivative in the logarithm of normalized press...

AJOP-T: A High-Order Hardening Law for Continuous Teardrop Bounding Surface Plasticity

Soft-ground finite-element analyses commonly reduce curved Oedometer compression to one constant slope, obscuring where stress-level curvature affects boundary-value predictions. AJOP-T embeds the differentiable Arc Joint via Optimum Parameters map in continuous teardrop bounding...
