MDSolids is educational software for students taking the Mechanics of Materials course (also commonly called Strength of Materials or Mechanics of Deformable Solids). This course is typically a part of civil,mechanical, and aerospace engineering programs and a number of related programs.

The software features educational routines for beams, flexure, torsion members, columns, axial structures, statically indeterminate structures,trusses, section properties, and Mohr's circle analysis including stress transformations and strain transformations.
