Multiscale material models are being increasingly applied for high-level simulation of complex materials, such as continuous reinforced material products (unidirectional and woven product forms). These multiscale material models require input data from a minimum of experimental tests, which are then used to characterize a multiscale material model that can be used in structural simulations within a variety of commercial finite element solvers, including OptiStruct, RADIOSS, Abaqus, and LS-Dyna. Using these models, it is possible is to predict the performance of layups from single layer properties, as well as performance of these composites under complex loadings. We present a framework where the required experimental data are collected, including a process for maintaining traceability and consistency of the experimental data using the Matereality software. Experimental test data are transmitted to the HyperWorks Multiscale Designer software for development of an appropriate multiscale material model. The resulting multiscale material model data is stored within Matereality linked to the source experimental data. Different manufactured layups are tested and compared to simulation in a validation step which provides a measure of the solution accuracy.

Material Wizard provides two options to create a new material file, Custom: If you have property data of a new material, you can select Custom to add the property data into Material Wizard. From Exterior Sources: If you find a new material in other sources, you can convert other format of the material file into Moldex3D format of the material file.

Propos recueillis par Olivier Guillon : Pierre-Pascal Bouf représente désormais DatapointLabs en France et plus largement en Europe si nécessaire. Celui-ci nous fait part de l’ambition de l’entreprise spécialiste dans les essais de matériaux et dévoile sa stratégie dont le succès passera inévitablement, selon lui, par une approche de partenariat avec ses clients, en particulier ceux de l’automobile.

Physically accurate simulation is a requirement for initiatives such as late-stage prototyping, additive manufacturing, and digital twinning. Simulations use mathematical models to replicate physical reality. Verification and validation (V&V) is an important step for high-fidelity simulation. While verification is a way to check the accuracy of these models, factors such as simulation settings, element type, mesh size, choice of material model, material parameter conversion process, quality and suitability of material property data used can have a large impact on simulation quality. Validation presents a means to check simulation accuracy against a physical experiment. These validations are a valuable tool to measure solver accuracy prior to use in product development. Confidence is gained that the simulation replicates real-life physical behavior.
