Plastic Deformation of Pure Polycrystalline Molybdenum
This chapter presents an overview of the experimental and theoretical investigations of the quasi‐static and dynamic, room temperature, mechanical response of a commercial‐purity polycrystalline Molybdenum material. It also presents the quasi‐static monotonic tensile and compression data on the material. The chapter discusses Taylor impact tests. It describes the constitutive framework considered for modeling the observed behavior which simultaneously takes into account the anisotropy and the difference in yielding between uniaxial tension and compression. The chapter also describes the procedure for calibration of the parameters from compression and uniaxial tension data on smooth tensile specimens. To characterize the strain rate sensitivity of the material, high‐strain‐rate compression tests were conducted using a split Hopkinson pressure bar system. A comparison between the quasi‐static uniaxial tension and compression data indicated that the material has tension‐compression asymmetry.
