GENERAL DESCRIPTION EnFEM is a general-purpose finite element analysis software for simulating 2D mechanical behaviors of solid materials sub-jected to various loads. EnFEM is able to perform plane-strain, plane-stress, and axisymmetric analyses with an emphasis on solving problems in geotechnical engineering. EnFEM is equipped with a variety of linear and non-linear material mod-els, boundary conditions, and element types, to provide users a full array of analysis options necessary for geotechnical and structural applications, from simple to complex.

With material models including von-Mises, Mohr-Coulomb, Drucker-Prager, Duncan-Chang, and modified Cam-Clay ap-plicable to granular and cohesive material such as soils, these capabilities make EnFEM the ideal tool for applications involv-ing soil-structure interactions seen in the design of underground culverts, retaining earth structures with tieback and soil nailing, pile-stabilized earth slope, and more.

LIST OF FEATURES• CAD-like interface for geometry creation/modification, as-

signment of analysis parameters, and post-processing. • Abundant material library with the following material mod-

els included; linear elastic, Tresca, Mises, Mohr-Coulomb, Druker-Prager, Duncan-Chang hyperbolic, and Modified Cam-Clay.

• Multi-stage analysis for simulating sequentially applied loads, as well as geostatic (initial) soil stresses, and excavations.

• Soil-structure interaction with computational contact analysis, capable of simulating material separations and sliding.

• Powerful mesh generator to generate first or second-order, quadrilateral or triangular finite element meshes, in either structured, unstructured, or combined meshes.

• Nonlinear direct solver based on multithreading and parallel processing optimization.

• OpenGL based graphics technology to plot contours accu-rately and quickly.

• Multiple output options including; contour plots, vector plots, XY-plots, cutline plots, and animations, for a wide array of categories and variables - including integrations (moment and shear), and interactions.

• Digital (PDF) documentation manuals - User's Manual, Technical Manual, and Example Manual.

• Completed examples files and accompanying instructional manual (Example Manual) to help users quickly learn the program, through common geotechnical and structural en-gineering problems.
