4a Impetus builds up an efficient and reliable process, using realistic testing methods and processing a validated material card. Recent developments of new test methods for 4a Impetus satisfy the needs of complex material models as well as the expectations with regard to simple and favorable tests.
The whole process to determine validated material cards is included in one software solution, starting with testing up to a speed of 10 m/s. The intuitive user interface is divided into four main areas symbolizing the experimental sequence. Automatically finite element models are build-up by using the underlying test database. The whole information from testing is transferred into finite element model and compared with the simulation results. In the area optimization the material card is determined by reverse engineering.
Different material models are implemented for example:
- Purely elastic
- Elastic plastic
- Elastic viscoplastic
- and many more!
Behind these material cards lies a set of predefined parameterized master material cards, used as starting point. One of the main focuses is the generation of strainrate dependent material cards used in impact and crashworthiness simulations.
As final result 4a Impetus is able to deliver a validated material card for Abaqus.
