To manufacture semi-finished hybrid workpieces with tailored properties a finite element simulation assisted process chain design was investigated This includes the process steps of cross wedge rolling hot geometry inspection induction hardening and fatigue testing The process chain allows the utilisation of material combinations such as high-strength steels with low-cost and easy to

COMSOL Multiphysics Software

Modeling with COMSOL Multiphysics means being able to move between simulating electromagnetics structural mechanics acoustics fluid flow heat transfer and chemical reactions phenomena or any other physics modeled by a system of PDEs in one software environment You can also combine physics phenomena from these areas in a single model The COMSOL Desktop user interface provides you

COMSOL MEMS TUTORIAL PDF - The Application Gallery features COMSOL Multiphysics tutorial and demo app files pertinent to the electrical structural acoustics fluid heat and Use prestress static and normal modes to analyze structures subjected to initial stress and model the effect of the initial stress state on the structures

The actual problem is the modeling of the stresses and strains after melting temperature So during welding one calculates stresses and strains until the melting temperature But because fluids can not transmit normal forces (and melted metal is considered as a fluid) it is required somehow to remove the material history/ to set element's

Let's look at a case from the COMSOL Multiphysics Model Library: the stresses and strains in a wrench This is a structural model of a combination wrench The provided CAD geometry has some relatively complex sculpted surfaces and fillets and blends which result in small faces in some parts of the model

2018-4-19The shear strains give an isochoric deformation that is a deformation without volume change The relative volume change is for small strains given by the sum of the direct strains: Changing the Perspective If we take the deformed shape as the starting point of the analysis it is possible to perform a similar development of the theory

In structural mechanics we solve for the displacement field bf{u} and compute the stresses from the strains bf{sigma =C : epsilon} where strain is defined in terms of the gradient of the displacement field: epsilon = 1/2 bf{ [ (nabla u)^T + nabla u] } When you think of the stress as being the gradient of the displacement field it
