Topology optimization mathematical model The structure topology optimization studies the distribution and composition of structural materials in the design space.
Different material interpolation models will get different calculation models.
The material interpolation model of variable density method mainly include: SIMP (Solid Isotropic Material with Penalization) model and RAMP (Rational Approximation of Material Properties) model, etc.
