The paper analyses the mesostructure of structural elements lattice aircraft shells – ribs consisting alternating layers equal thickness and made from unidi-rectional CFRP pure matrix material. In experimental studies, elastic characteristics unidirectional were obtained under three-point bending transversal compression. As a result, longitudinal modulus elasticity layered composite turned out ...

In this research, wave propagation analysis in polymeric smart nanocomposite micro-tubes reinforced by single-walled carbon nanotubes (SWCNT) conveying fluid is studied. The surrounded elastic medium is simulated by visco-Pasternak model while the composite micro-tube undergoes electro-magneto-mechanical fields. By means of micromechanics method, the constitutive structural coefficients of nano...

Classical solution methods in fast Fourier transform-based computational micromechanics operate on, either, compatible strain fields or equilibrated stress fields. By contrast, polarization schemes are primal-dual whose iterates neither nor equilibrated. Recently, it was demonstrated that may outperform the classical methods. Unfortunately, their power critically depends on a judicious choice o...

a new model is proposed in this research to calculate the longitudinal strengthof unidirectional e-glass reinforced polymer composites exposed to sulfuricacid environment, using a micromechanics model. in the proposed method,it is assumed that the residual strength of the degraded composites under acidic environment can be calculated by knowing the degraded strength properties of the constituen...
