Tensorial Generalization of Uniaxial Creep Laws to Multiaxial States of Stress,s found in experimental investigations. For engineering applications it is very important to generalize . relations to . states of stress. This can be achieved by applying .,as pointed out in detail in this chapter. It is illustrated that the scalar coefficients in tensorial constitutive equations c

Viscoelastic Materials, capacity for materials to store mechanical en­ergy when deformed by loading, and to set free this energy completely after removing the load. In viscous flow, however, mechanical energy is contin­uously and totally dissipated. Viscoelastic materials . and . en­ergy in varying degrees during loading/

Michael Schemmann,Wolfgang Seitterhion in our industries are largely plastic solids. Investigation leads us to the belief that plasticity is made up of two fundamental properties which have been made ‘yield value’ and ‘mobility’, the former being dependent upon the shearing stress required to start the deformation and the mobility b

Influence of Process Parameters on Weld Bead Geometry and Mechanical Properties in GTAW,rs, such as welding current, welding speed, gas flow rate and groove angle. This work concerns with mild steel plate joining with bevel angle (30°–50°) and also using filler material same as the base metal. The quality of welds will depend on the modeling of weld bead shape.
