Stress and Strain Fields in a Plate of Stress State Dependent Material Properties

Authors: Lomakin E. V., Shchendrigina O. P.

The paper analyzes the properties of the constitutive relations proposed to describe the behavior of materials whose deformation diagrams depend on the type of external forces. In this case, various forms of nonlinearity arise, related to the dependence of the properties of materials on the type of the stressed state, the nonlinearity of the deformation diagrams, and the relationship between the shear and volume deformation processes.

Multimodulus Behevior of the Grained Composites on the Base of Unsaturated Polyetheres

Authors: Bessonov D. E., Zezin Y. P., Lomakin E. V.

The results of the investigation of elastic properties of grained composite based on the unsaturated polyetheres were presented. This material was designed to substitute natural rocks in civil and mechanical engineering. The experimental values of elastic modulus and the Poisson‘s ratio under the tension and compression were obtained. It was shown that the investigated composite exhibits the dependence of elastic properties on the type of the stress state.
