Reasons and benefits of using JAXA Supercomputer System

High-performance computing is necessary, because numerous three-dimensional nonlinear finite element analyses need to be performed to design test articles at the element level of aircraft structures.

Achievements of the Year

Three-dimensional nonlinear finite element analyses were conducted on metallic skin/stringer panels at the element level under compressive loading, and the buckling loads and buckling induced deformations of the panels were studied.

The main results obtained from the analyses for panels with different lengths L (Fig. 1) are as follows.

(1)The buckling load (maximum load) was dependent on the panel length, and the buckling load for Case 1 (L/L1 = 1) was highest (Fig. 2).

(2)Except for Cases 1 (L/L1 = 1) and 9 (L/L1 = 1.17), the buckling induced deformations (out-of-plane deformations) of the panels were similar (Fig. 3).

(3)The finite element analysis results are useful for designing element test articles.
