Peculiarity of she shaped-charge liner collapse concerning the unevenness in its cross-section

For harmonical components of the unevenness, simulating the misalignment of the inner and the outer surfaces of the shaped-charge liner the functional connections to estimate the angular deviation of the shaped-charge jets from symmetry axis were developed. Numerical calculations in CAE system ANSYS AUTODYN for the process of collapse of the ring with the consideration of alteration of its thickness in accordance with harmonical components of the unevenness were ran to estimate the distortion of cross-sectional shape of the shaped-charge liner throughout the process of collapse. Obtained results can be used in quantitative estimations of the influence of the inaccuracies of the shaped-charge liner on geometrical and kinematical characteristics of the shaped-charge jets.
