The MECH-Gcomp software was developed by the Composite and Nanocomposite Materials Research Group (GCOMP) of LAPOL/UFRGS, aiming at providing a practical, quick and didactic way to compute thermal, mechanical and hygroscopic properties of composite materials.. Besides predicting the composite properties based on reinforcements and matrix properties via micromechanics theories, 13 different failure criteria have been implemented for the failure analysis of laminae. It is also possible to obtain the ABD matrix of laminates, and there is a module dedicated to the analysis of bending and buckling sandwich beams. This way, MECH-Gcomp encompasses a great part of the mechanics of composites, and it’s available in Portuguese, English and French.

The main difference of MECH-Gcomp over related software lies in its micromechanics module, where different approaches from different authors are available for the calculation of a property, leaving the final choice to the user. The software also covers a wide range of reinforcements for continuous and discontinuous, unidirectionally or randomly oriented fibers, as well as hybrid composites with two different fibers, particulate composites and nanocomposites. A comprehensive database with properties for many reinforcements and matrices is included, and the user can create and save new materials, which are then only available in his private account. Furthermore, for improved didactics, the software allows the user to plot the properties obtained via micromechanics as a function of the reinforcement content or its orientation angle, and the plots can be exported as images or raw data for external spreadsheets.
