Due to a combination of advantages, high-performance steel components, especially for automotive manufacturing applications, are generally forged parts. In the forging industry, bainitic steels being increasingly used, because they can reduce processing chain and energy consumption. this case, microstructure be obtained immediately after forging, with controlled cooling, without any subsequent ...

In recent years, cohesive zone models (CZMs) have been developed and widely used in numerical simulations to account for crack initiation and propagation in different materials and structures. This study is focused on the modeling of the elastoplastic damageable behaviour of ductile materials. The damage is associated with a cohesive behaviour of the interface between the purely elastoplastic s...

Two Way Shape Memory Effect (TWSME) involves thermomechanical routines which produce some plastic deformation or complex dislocation arrays during the training procedure. The results of TWSME obtained by these thermomechanical training routines are not as good as would be expected because new dislocations are generated during thermal cycling. These dislocations may interact with those that prov...

Analysis of the thermomechanical interactions of fusion blanket materials and physical elements, particularly those involving particle bed design concepts, have been performed. The results show that the stress caused by the high thermal expansion of the blanket particle bed material is not excessive enough to be of concern for the structural material. However, its magnitude could lead to cerami...

The heat flux on the divertor plate of a fusion reactor is probably one of the most limiting constraints on its lifetime. The current heat flux profile on the outer divertor plate of a device like the International Thermonuclear Experimental Reactor (ITER) is highly peaked with narrow profile. The peak heat flux can be as high as 30-40 MW/m 2 with full width at half maximum (FWHM) of the order ...

Synopsis : The transient network model of Green-Tobolsky [1946], Yamamoto [1956] and Tanaka-Edwards [1992] is formulated within the frame of thermodynamics of irreversible processes, using as a fundamental quantity the chemical potential associated to the connection of strands to the network and treating these connections as chemical-like reactions. All thermodynamic quantities are thus natural...
