Nuclear power plant safety under cover in the plane hit the plastic dynamic analysis of axisymmetric

Movement and; application hit _, \ one by one ... the dynamic elastic 23'67, Bear: s II; Figure 11 Amber shell cap the number of hoop stress distribution is only 1.032 * (which B refers to the dynamic displacement power factor response and the impact of static load and peak load calculated for the static displacement ratio) so if! bomb Sui Dynasty line, then as long as the calculation of static analysis can reflect the worst when the elastic dynamic situation. 2, the elastic-plastic dynamic response, dynamic coefficient of 1.831, l2 store plastic zone development plan and in the stress distribution and so have many new features and phenomena,[link widoczny dla zalogowanych], dynamic: even in a prominent special. Therefore, the security structure of this plastic shell analysis is very necessary. 3, described the structure of the aircraft impact load caused by elastic and plastic response,[link widoczny dla zalogowanych], throughout the entire structure, and j ? in the impact area near the nonlinear dynamic response, and most areas of the structure remains flexible for the dynamic response of coral the entire roof structure, the crushing failure phenomenon occurs or at a local scale,[link widoczny dla zalogowanych], in which approximately lO. Cone of the plastic zone. '4, In order to get a more accurate structure, material behavior. Must also be used to simulate crack propagation of concrete, reinforced the role of the model. Material changes in performance, etc. as appropriate. Such as the layered structure model. Combined material model for analysis. 5, containment cover the local loads. Saddle slow with localized plastic zone generated by the structure of ring A Venturi:. Tin this. To get more accurate results, it must be more complex jf the skid system for further study. 2 Eucalyptus plant containment cover under the plane hit the plastic dynamic analysis of axisymmetric 25 reference: Xiao literature r1] R.
