Engineering Services Root Cause Failure Analysis Materials Characterization Studies Stress Analysis and Finite Element Analysis (FEA) Forensic Engineering Materials Characterization Studies Materials compatibility is the evaluation of the environment in which a component will function to determine if the material is compatible with the environment in which it is to function. The services provided by MMT are intended to assist clients in the selection of materials from which components are to be fabricated.  The analysis processes may result in a list of materials that are compatible with the design criteria and\or the identification of critical properties to be used in the selection of materials.
