【Abstract】 Uniaxial tensile behavior of nickel foam under four different strain rales and four different temperature levels separately is studied. The results show that mechanical properties (modulus and strength) of nickel foam increase with increasing strain rate, and decrease with increasing temperature. Expressions of modulus and strength of nickel foam, varying with relative density, temperature and strain rate are given in this paper.更多还原
