In this paper a scalar-valued isotropic tensor function is considered, the variables of which are constitutive tensors of orders two and four, for instance, characterizing the anisotropic properties of a material. Therefore, the system of irreducible

Provides a short survey of recent advances in the mathematical modelling of the mechanical behavior of anisotropic solids under creep conditions, including principles, methods, and applications of tensor functions. Some examples for practical use are

A three-dimensional creep damage model for polycrystalline materials with parallel flat microcracks is presented, employing a damage vector. This model describes simultaneously damage induced anisotropy, different damage in tension and compression, a

In order to calculate the buckling load of a rectangular plate, the analytical approach is used in this study. The plate is assumed to be simply supported on four edges and loaded by uniform stresses along the edges. If the plate is slender, the buck

A continuum damage mechanics model for the dislocation creep response associated with the growth of parallel planar mesocracks in initially isotropic materials is presented. The model describes simultaneously different damage development in tension,

In this study the plastic buckling analysis of a circular cylinder under axial compression is carried out considering plastic compressibility. For the stability analysis, the linearized finite element equation is derived and the general elastic-plast

The mechanical behaviour of anisotropic solids requires a suitable mathe matical modelling. The properties of tensor functions with several argument tensors con stitute a rational basis for a consistent mathematical modelling of complex material be h
