Modeling and Analysis for the Response of Structures (MARS) is a powerful and robust object- oriented computational software for simulating the mechanical response of structural systems subjected to short duration events. It is based on a dynamic explicit algorithm and it implements all the capabilities and versatility of a general finite element code. In addition, MARS features some unique techniques, such as the Lattice Discrete Particle Method (LDPM) and adaptive remeshing algorithms for shell and solid meshes, which facilitate the solution of problems involving structural break-ups, fragmentation and post-failure response under extreme loading conditions.

This web site provides an overview of the MARS code and ES3’s capabilities in applied structural mechanics, with examples of our work in:

• Deformations and Failures,
• Dynamic System Modeling,
• Component Models, and
• Animations

ES3’s capabilities and the MARS computational tool is best understood by our

• Object Oriented Approach,
• Analytical Methods, and
• Verification and Validation efforts.
