Role of texture in spin formed Cu shaped-charge liners
Spin formed Cu shaped charge liners are known to produce a rotating jet and are used for the spin compensation effect. The causes of spin compensation can be mechanical in nature or can be grounded in microstructural issues such as texture, residual stress, grain size, and morphology variations. This investigation focuses on determining specific microstructural parameters that influence jet rotation and modeling the jet formation process using anisotropic plasticity in a 3-D finite element framework. The experimental texture has been mapped onto a finite element grid for 3-D modeling to obtain the normal-shear deformation coupling information needed to construct a plastic flow potential. Simulations of a collapsing ring and extending rod demonstrate rotation.
