Abstract

In this paper, we develop an automated software for in-plane structural analysis of composite laminated structures. The developed software supports various failure criteria and reports the analysis results considering user's convenience. It also provides batch job analysis function based on parallel processing technique. To verify the performance of the software, we compared margin of safety(MS) calculated in the software to those obtained from in-house method and the specimen experiment. As a result of comparisons, there was an error of less than 0.01 in the in-house method and it is within about ${\pm}10%$ with the specimen experiment. In addition, we confirmed the improvement of execution speed of batch job analysis based on parallel processing technique.

본 논문에서는 복합재 적층 구조물의 면내 구조 해석을 위한 자동화 소프트웨어를 개발한다. 개발된 소프트웨어는 다양한 파손 기준을 제공하며 사용자의 편리성을 고려하여 해석 결과를 출력한다. 또한 병렬처리 기법에 기반한 일괄 처리 해석(batch job analysis) 기능을 지원한다. 구현된 소프트웨어의 성능을 검증하기 위하여 소프트웨어에서 계산된 안전 여유와 자체적으로 사용 중인 in-house 방식과 실제 시편 실험에서 얻어진 안전 여유간의 비교를 수행하였다. 비교 결과 in-house 방식과는 0.01 이하의 오차가 있었으며 시편 실험과는 약 ${\pm}10%$ 이내의 오차가 존재함을 확인하였다. 또한 병렬처리 기법을 적용한 일괄 처리 해석 작업의 실행 속도 개선을 확인하였다.
