Abstract

The purpose of this paper is to develop the structural analysis for prediction of the sideward loads acting on the inner wall of the rocket engine nozzle. Three-dimensional structural analysis was performed using the facet shell element. This was created by combining the optimal triangle membrane element (OPT) with the discrete Kirchhoff triangle (DKT) plate bending element. The laminated composite material was considered by modifying the formulation of stress-strain relationship so as to include the membrane-bending coupling effect. For the time transient analysis, Newmark implicit time integration method was used. To consider the realistic engine nozzle structure, validation of equivalent structural modeling was conducted. Parallel computation using FETI-local method was utilized to alleviate the computational cost due to discretization of large size engine nozzle structure.
