FE Analysis of Contact Interaction Between Rigid Ball and Woven Structure in Impact Process

The current paper presents the results of finite element solution of the problems simulating contact interaction between woven structures and striker in the form of rigid ball. The woven structure is represented by a great number of the fibers braided in such way that each of them can come into contact interaction with others. In this paper the analysis results for ball impact direction effect on the woven structure dumping properties was demonstrated. For simulation of the impact process and subsequent multiple contact interaction between woven structure fibers FE mesh containing about 1 million degrees of freedom was used. The efficiency of contact algorithm realization in finite element software LS-DYNA is visually presented. The zone with largest contact pressure and redistribution of contact interaction zone in impact process was analyzed
