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.

摩擦力作用下多孔复合材料的接触问题

摘要

考虑到接触域中的摩擦力源于具有平坦或抛物线型基体的模具的运动,因此对于非均质流体饱和半空间考虑了接触问题。

为了考虑基体的内部微观结构,使用了比奥模型。边界问题借助于傅里叶变换减少到具有对数奇异性的核的第一类积分方程。积分方程的解已使用搭配方法构造。研究了孔隙率和摩擦系数对充油苯酮基复合材料接触应力的影响。使用微力学和有限元模拟方法确定了复合材料的机械模量,并与实验结果进行了比较。
