 Crushable foam models target energy-absorbing foams and similar crushable media. Jointed material behavior represents continua containing dense sets of joint surfaces, such as sedimentary rock. Concrete is represented by multiple models: smeared cracking in Abaqus/Standard, brittle cracking in Abaqus/Explicit, and concrete damaged plasticity in both solvers.
 
+[[Finite-Elements-in-Plasticity-Theory-and-Practice|Finite Elements in Plasticity: Theory and Practice]] provides the classical finite element plasticity context for this page's pressure-dependent models. It treats Mohr-Coulomb and Drucker-Prager criteria alongside metal-style criteria and highlights the role of non-associated flow rules for frictional materials.

 ## Why It Matters
 
 These materials cannot usually be modeled by metal-style pressure-insensitive plasticity. They require pressure-dependent yield surfaces, inelastic volumetric strain, tensile cracking, crushing, or damage recovery effects that are tied to element choice, confinement, and loading path.
