Axisymmetric pre-buckling deformation from BIGBOSOR4 of a nonlinearly optimized configuration analogous to the “mich1” configuration except that YPLAT

Fig. 35 Axisymmetric pre-buckling deformation from BIGBOSOR4 of a nonlinearly optimized configuration analogous to the “mich1” configuration except that YPLATE(1) < YPLATE(2). This configuration in which YPLATE(1) < YPLATE(2) contracts in the axial direction under the applied uniform external lateral normal pressure, and the nonlinear load-ENDUVS curve exhibits a softening characteristic with increasing pressure, as shown in Fig. 36.
