In this report, following the preceding paper, the large plastic deformations of the corrugated bulkhead are discussed under transverse impact at center such as considered inelastic imapct when all edges of the bulkhead are clamped.We are first concerned about both maximum deflections and deformations, in the case of plate material having ideal characteristics of plastic bending moment M_p(θ^^^<・・>) such as expressed by M_<p0>γ_1 (1+γ_2θ^^・) and keeping the ratio of two plastic moments due to bending or twisting, independent of angular velocity θ^^・. Then the criterion of fracture for the impulsive load to the plate is given applying the theory of the propagation of plastic strain along the longitudinal axis of corrugated bulkhead. In theoretical analysis, the shape of impulsive load is assumed rectangular between impact duration 2T.
