Study of the Effects of Thermomechanical Coupling Near Stress Concentrators in Viscoelastoplastic Bodies

A model is developed to investigate thermal effects in elastoviscoplastic bodies. It allows us to obtain some quantitative and qualitative information on the stress–strain state of a body and to carry out a nondestructive diagnostics of internal defects, which are stress and strain concentrators. The problem on the plane stress state of a rectangle with a hole is considered as an example. The plate is made of steel and aluminum alloy. The variation in the temperature on the external contour of the body under monotonous and cyclic tension in the elastic and plastic domains is studied     

Thermomechanical Coupling Effects Near Defects in Inelastic Bodies

Models used to study thermal effects in elastoviscoplastic and viscoelastic bodies deformed under monotonic and harmonic loading are considered. They allow us to obtain qualitative and quantitative information on the thermomechanical state of the material. Numerical results can be used in a nondestructive analysis and in predicting thermal fatigue failure of inelastic bodies     

Investigation of mutual longitudinal displacements of structural elements upon welding

We present the results of experimental investigation and control over mutual displacements of elements in the process of welding of butt and T-joints and develop a computational method for determination of these displacements and estimation of their influence on the accuracy of welded structures.
