Lattice Element Method (LEM)

by Maksymilian Jasiak

LEM is a numerical method that is used to investigate fracture development in rock materials. It is a novel approach that does not require fracture path to be predefined. Fully coupled 1D beam-element lattice networks are used to represent 3D… Read More »Lattice Element Method (LEM)

Finite Element Method (FEM)

by Maksymilian Jasiak

FEM is a numerical method that utilizes discretization to develop then solve a system of equations to numerically approximate the solution to differential equations of interest. Beyond geotechnical modeling, FEM is very frequently used for modeling structural analysis, heat transfer,… Read More »Finite Element Method (FEM)

Material Point Method (MPM)

by Maksymilian Jasiak

MPM is a particle-based method that represents material as a collection of material points. Each material point’s movement is determined via solving Newton’s laws of motion. MPM is a hybrid Eulerian-Lagrangian approach, which uses moving material points and a fixed… Read More »Material Point Method (MPM)
