Temperature-porosity-dependent elastic modulus model for metallic materials

Abstract Elastic modulus plays a key role in the application of porous metallic materials. However, to best our knowledge, few attempts have been made model simultaneous dependence elastic on temperature and porosity for The present article contributes rational temperature-porosity-dependent materials with all parameters having definite physical significance. can well predict moduli materials, from extremely low ultrahigh temperature, dense material about 0.9 porosity, reference an easy-to-access modulus. In special case, when intrinsic [ M ] = 2 critical P C 1, phenomenological parameter-free predictive be obtained. applied matrix Poisson ratio is 0.1 < v 0.4 Young’s 0.17 0.27 shear modulus, which covers most
