The objective of the software is to provide Multi-scale analyses to predict the nonlinear micromechanical behavior of materials and structures
Besides offering many years of eXpertise, e-Xstream offers the solution that translates a multi-scale approach into software.
The usage of Digimat follows three major strategies:
Digimat Material modeling for Material Engineering
The purpose of material engineering is to take a simulation approach for the identification of promising candidates for new composite materials, thereby reducing the amount of experiments needed. This helps to save money and to reduce the time needed to develop new materials.
In research the approach allows to gain insight into and to understand mechanisms that dominate the macroscopic material properties but actually arise from its microscopic composition.
Digimat Material modeling for Process Simulation
Digimat provides process simulation solutions for the additive manufacturing of polymers. It helps process engineer to anticipate manufacturing issues and optimize part quality (ex: minimize warpage and residual stresses) by predicting the relative influence of the various process parameters.
Digimat Material modeling for Structural Engineering
The purpose of structural engineering is to design full composite parts. The focus is on the part performance as it depends on the material characteristics and the manufacturing method and conditions that were used for the individual design.
Key to this challenge is a material model that correlates to experimental behavior as closely as possible. For this purpose a reverse engineering procedure is used that results in the parametrization of micro-mechanical models and their adaption to a set of anisotropic material measurements to meet the global composite performance best possible.
Such material models can now read locally different micro-structure information from various sources and convert them into a local material property. A fully coupled analysis results in a simulation model with individual material properties described for each integration point in the Finite Element analysis. Coupled analyses are state-of-the art for the modeling of composite parts and have proven to match experimental observation perfectly on many occasions.
