Numerical Modelling and Finite Element Simulation of physical phenomena represent key elements among the CSM’s activities. They are devoted to both analysis and optimisation of in-service performances of components, sub-assemblies and complete structures, and the optimisation of traditional or innovative manufacturing processes and technologies. The final goal is often the identification of tailored technologies enabling the correct use of materials.
CSM optimally performs this activity in virtue of the full integration of virtual and real-world prototyping inside remarkable pilot experimental facilities, and a deep and consolidated experience on materials gained over twenty years, in providing methodologies and tools for the simulation of complex forming processes.
Conventional and innovative metal forming processes (e.g., sheet drawing, wire drawing, forging, sheet and pipes hydroforming, super plastic forming – SPF -, rolling, roll forming, bending & stretch bending, extrusion, tube rolling, etc.) can be simulated in order to relate the the process variables to the final quality of the component.
Likewise, these software permit to better relate the heat treatment or welding processes to the material phases distribution, residual stresses and thermal distortion and estimate how they affect the material fatigue resistance.
Specific procedures are used to transfer the final stress-strain state after the forming process (residual stresses, material hardening) to the component for successive in-service performance assessments.
