Elastic and plastic properties of composites based on polytetrafluorene-ethylene
Based on the theory of elastic-plastic deformation, general dependence voltage increment on incremental strain is reached. The analytical form of dependence is fixed in analytical form for uniaxial stress state. The identification task of elasto-plastic model with line isotropic hardening is viewed. The algorithm for parameters characterization of this model, according the stress-strain curves, getting with the standard mechanical tests of materials is represented. The certification of antifriction Fluvis carbon plastic deformation properties based on polytetrafluoroethylene is completed.
