Abstract : A survey has been made of the literature published previously on the inelastic behavior of shells subjected to dynamic loads. An experimental investigation has also been undertaken to examine the behavior of various cylindrical shell panels which were loaded with an impulse on the inner surface. The panels were fully clamped along the two longitudinal edges and free on the other two. The initial kinetic energy of the dynamic loads was sufficiently large to cause inelastic behavior and to produce maximum permanent transverse deflections of up to nearly twice the corresponding panel thickness. Tests were conducted on mild steel and aluminum 6061 T6 panels which had various thicknesses and an included angle of 90 degrees approximately. (Author)
