Such an analysis allows an engineer to assess the mechanical and physical properties to design an optimum composite composition in terms of advantageous mechanical properties and at the same time a good electrical discharge machining performance. Thermal residual stresses in the constituent phases and thermal and electrical conductivity of ZrO2-based composites are assessed by a Finite Element (FE) model using 2 dimensional SEM micrographs. The FE models are verified by comparing numerically calculated results with experimentally measured data.","PeriodicalId":132974,"journal":{"name":"Int. J. Chemoinformatics Chem.

Experimental dependences of mechanical characteristics on a swelling function are given for a series of polymer materials. One dimensional and three-dimensional linear-elastic models of body deformation with regard to influence of corrosive liquid media are suggested. A new phenomenon, bulging of a polymer strip rigidly fastened by both ends because of swilling forces, is established. The stability criterion is given for a strip made of a polymer material situated under the action of swelling forces only.","PeriodicalId":132974,"journal":{"name":"Int. J. Chemoinformatics Chem.
