This paper presents a qualitative explanation of the creep phenomenon based on the physical and chemical mechanisms that occur at micro and ultra-structural levels of wood during moisture diffusion. This part is then completed by the formulation of a

In most numerical simulations of welding, due to the very short times involved, viscoplastic effects are neglected. However an experimental mock-up developed at INSA has evidenced the possible importance of such effects, which must therefore be incor

In most numerical simulations of welding, viscoplastic phenomena are neglected, because of shortness of the process. The aim of this paper is to accurately assess the effect of such phenomena upon predicted residual stresses and distortions, through

In this paper the behavior of a disc made up of carbon manganese steel and subjected to an axisymmetric heating in its middle zone is considered. The applied thermal cycle generates localized metallurgical solid-solid phase transformations. Contrary

It has been long recognized that the buckling behaviour of thin-walled pressure vessels, subjected to axial loading, is characterized by a bifurcation on an asymmetrical mode. It is also known that the carrying capacity of this type of structure grea
