Abstract
A contact problem is considered for a heterogeneous fluid-saturated half-space considering friction forces in the contact domain originated from the movement of a die with a flat or and parabolic base. For to consider the internal microstructure of the base, Biot’s model is used. The boundary problem is reduced with the help of the Fourier transformation to a first-kind integral equation with a kernel having a logarithmic singularity. The solution of the integral equation has been constructed using a collocation method. The effect of porosity and friction coefficient exerted on the contact stresses in the oil-filled phenylone-based composite has been studied. The mechanical moduli of the composite have been determined using the methods of micromechanics and finite-elemental simulation, and compared with experimental results.
