AB  - This study deals with an elastomer body having a random 3D distribution of two types of inclusions: spheroidal mutually parallel voids and differently oriented reinforcing parallel elastomeric stiff spheroidal short fibers. By the effective field approach, the effective stiffness four-tensor as well as the effective thermal expansion two-tensor are formulated and found numerically. Simultaneous and sequential embeddings of inclusions are compared. Damage evolution is described by a modified Vakulenko's approach, the endochronic thermodynamics. A brief account of the problem of effective elastic and thermal symmetry is taken. The results of the theory are applied to creep of an elastomeric PU-based composite caused by triangular history of compressive stress.

AB  - In the present paper the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular cross section and cyclic bending of rectangular tube (box) will be studied in details. Hysteretic stress-strain loop for prescribed history of stress change is plotted for material modeled by series connection of three unite element. Also moment-curvature hysteretic loop is obtained for a prescribed curvature change of rectangular tube (box). One chapter of the paper is devoted to results obtained by FEM using Finite Element Code ABAQUS. All obtained results clearly show advantages of the Preisach model for describing cyclic behavior of elasto-plastic material.
AB  - U posmatranom radu Prajzakov model histerezisa je primenjen na modeliranje cikličnog ponašanja elasto-plastičnih materijala. Pri tome brzina nanošenja opterećenja i viskozni efekti se ne uzimaju u obzir. U radu se detaljno proučava problem aksijalnog naprezanja pravougaonog poprečnog preseka i ciklično savijanje pravougaone čelične cevi. Konstruisana je histerezisna petlja za zadatu promenu cikličnog opterećenja za materijal modeliran sa tri osnovna elementa. Takođe, histerezis momenat-krivina za čeličnu pravougaonu cev je konstruisan za zadatu istoriju promene krivine. U posebnom poglavlju se obrađuju rezultati dobijeni primenom MKE korišćenjem programa ABAQUS. Svi dobijeni rezultati jasno pokazuju prednost Prajzakovog modela kod opisivanja cikličnog ponašanja elasto-plastičnih materijala.
