The smeared approach modifies the material stress-strain law. It does not introduce physical gaps into the finite element mesh. Tensile Cut-Off Configuration : Limits the maximum allowable tensile stress ( σ3sigma sub 3 σtsigma sub t ) in the soil or concrete matrix. Yield Condition : σ3≤σtsigma sub 3 is less than or equal to sigma sub t Failure State : When tensile stress reaches σtsigma sub t

To model a crack, you must choose between a (distributed micro-cracking) or a discrete approach (explicit localized separation). The smeared approach modifies the material stress-strain law
: He checked the Tension Cut-off setting in the soil's constitutive model. By setting the allowable tensile strength to zero, he was telling PLAXIS: "The moment this soil pulls apart, it provides no resistance." The Calculation Phase Yield Condition : σ3≤σtsigma sub 3 is less

"The hydrostatic pressure is the culprit," Elias realized. The crack had filled with rainwater, creating a "water-filled tension crack" that exerted massive lateral pressure on the wall. He quickly updated the in his model, adding a "dry" crack versus a "water-filled" one.
