| Description |
A theory of long-term damageability is built for the fibrous composite materials with allowance for of the temperature effect. The process of damage of the composite’s matrix is modeling by the arising the stochastically located micropores in the matrix. The criterion of fracture of the unit microvolume is characterized by its long-term damageability, which is stipulated for dependence of the brittle fracture time on degree of closeness of equivalent stress to its limit value. For the arbitrary time, the equation of matrix damage balance (porosity) is formulated with allowance for a temperature component. An algorithm is constructed for evaluation of dependences of the matrix microdamage on time and the macrostresses on time. The corresponding curves are built. An effect of temperature on deformation and microdamage of material is studied.
