Mechanical Properties of Composite Engineering by Multivolume Micromechanical Modelling

Popis výsledku v původním jazyce

Engineering structures often consist of elements having the character of a periodically repeated composite structure. A multivolume micromechanical model based on a representative cell division into (ro)1x(ro)2x(ro)3 subcells with different elastic material properties has been used in this paper to derive macromechanical characteristics of the composite construction response to applied load and temperature changes. The multivolume method is based on ensuring the equilibrium of the considered volume on an average basis. In the same (average) way, the continuity conditions of displacements and tractions at the interfaces between subcells and between neighbouring representative elements are imposed, resulting in a homogenization procedure that eliminatesthe discrete nature of the composite model. A parametric study is presented illustrating the influence of joint thickness, joint filling material properties and the quality of bonding between block and filler elements.
