Abstract:
Because of the softness of cabin material and thin bulkhead,a very distinct shape change oc- curs under the action of internal pressure.The stronger nonlinear relationship between load and bulkhead dis- placement makes the calculation very complicated.For simplicity and considering the influence of big shape change approximately all of load is imposed in several divided stages.The effect from the shape change, caused by previous stages of load,must be figured when next stage of load is imposed.A formula of small shape change is used to calculate each stage of load.In this paper,the main idea is that a nonlinear problem of shape change is linearized in dividing section.
