Abstract:
In this paper the authors on the basis of the general heat equation have obtain a differential equation describing the temperature enhancement (self-heating) by cycling of nonlinear elastoviscous composite materials as a function of imposed strain amplitude and frequency. One assumes homogeneous temperature field. Thermo-elastic and thermo-damage connectivity have been neglected. It is acceptable, due to the small cross section of the samples and the relatively small deformations. Natural and forced convection to describe the heat losses in the surrounding have been take into account. The dissipation energy has been divided into heat loss and damage development energies in order to take into account the damage by cycling loading. Some comparisons with experimental results for glass fiber composite (30% glass fibers) when take into account the heat losses in the surrounding confirm the applicability of the proposed approach. The surface temperature of the samples was measured with laser infrared thermograph.
