Embodiment Construction
[0035] The embodiment of the present invention provides a method for optimizing the damage tolerance of the integral wall panel with ribs, such as figure 1 shown, including the following steps:
[0036] S1, determine multiple groups of parameters to be optimized for the overall wall panel of ribs, and form an optimization matrix;
[0037] S2. Select a set of rib parameters in the optimization matrix;
[0038] S3, establish a finite element model of the overall wall plate containing at least two ribs, and assume a penetrating crack with an initial length a at the center skin;
[0039] S4, expanding the penetrating crack in the finite element model, and calculating the crack growth life under the set of rib parameters;
[0040] S5. Comparing the crack propagation life under different rib parameters, selecting the rib parameter with the largest crack growth life as the optimal result, and the damage tolerance performance of the overall wall plate is the best under the optimal r...
