Creating imperfections in LS-DYNA® using the *PERTURBATION keyword

Imperfections for buckling and other instability problems can be created in LS-DYNA® using the *PERTURBATION keyword. These imperfections and perturbations are also known as stochastic fields. Modeling these imperfections is crucial for instability problems such a buckling analysis.
