When: Feb. 17–18

Full announcement and registration here

Instructor: Charles E. Anderson Jr., Director, Engineering Dynamics Department, Mechanical Engineering Division, Southwest Research Institute

About the course: This two-day short course will focus on the penetration response of metallic and brittle materials. The first day will focus on the penetration response of metals, and the second day will focus on the penetration response of brittle materials such as ceramics and glass.

Topics on the first day include similitude modeling; semi-infinite penetration; perforation; ballistic limit analysis; analytical modeling (hydrodynamic theory, Tate, and Walker-Anderson); deviations from hydrodynamic theory; rigid-body penetration; L/D effect; high-velocity effects; replica scale modeling; and impact inclination effects. Numerical simulations will be used to provide insights into the mechanics and physics of penetration.

Topics on the second day include failure waves; reverse ballistic experiments of gold rods into silicon carbide; penetration into intact, predamaged, and powder silicon carbide; penetration into glass by long rods, short rods, and spaced short rods; experimental methods for determining constitutive parameters for failed material (borosilicate glass and boron carbide), an analytical model for dwell; dwell and post-dwell penetration (silicon carbide and glass); ballistic experiments into transparent armor; and measurement of crack and damage velocities in glass. Again, numerical simulations will be used to provide insights into the mechanics and physics of penetration.

Charles E. Anderson Jr. is director of the Engineering Dynamics Department of SwRI, where he oversees and manages a multidisciplinary effort to investigate the dynamic response of materials and structures. He has been active for over 35 years in numerical simulation of explosive-metal interactions and impact mechanics, using numerical simulation for fundamental and applied studies. Dr. Anderson is recognized for his leadership in combining numerical simulations with experimental data to develop advanced models of the response of materials to shock, impact, and penetrate. He is also recognized for his experience in developing relevant test plans to include appropriate and state-of-the-art diagnostic equipment. He has been the organizing chair and technical chair for a number of international conferences/symposia. Dr. Anderson continues to serve on government advisory boards dealing with issues in computational mechanics, penetration mechanics, and the response of materials at high loading rates, areas in which he has published extensively. He is an associate editor for the International Journal of Impact Engineering, a fellow of the American Physical Society, and a fellow of the International Ballistics Society. In 2000, Dr. Anderson received the Distinguished Scientist Award from the Hypervelocity Impact Society for his contributions to penetration mechanics, numerical simulations of penetration mechanics, and modeling dynamic material response. In September 2014, he was elected a ballistics science fellow of the International Ballistics Society in recognition of his "outstanding research in terminal ballistics."
