Abstract

Energy-absorbing behavior of laminated plate structures with multiple delaminat ions T. Yoda," & K. Ando& "Department of Civil Engineering, Waseda University, 3-4-1 Ohkubo, Shinjuki-ku, Tokyo, 169 Japan ^ESI Asia, 7-2-301 Ohkamachou, Shibuya-ku, Tokyo, 151 Japan ABSTRACT The concept of an energy-absorbing laminated plate structure with artificially introduced multiple delaminations is proposed for use in crashworthiness design. Experimental investigation was performed to study an impact performance of delaminated laminates subjected to axial compression, where achieving a high energy absorption performance is examined by using failure initiation technique. Although buckling load decreases with the introduction of delaminations, postbuckling behavior is altered to more desirable energy-absorbing characteristics. Delaminations can thus be used to improve the impact performance of laminated plate structures. INTRODUCTION L
