description A method (500) for analyzing a structure includes processing nondestructive inspection (NDI) data (112) for a multi-layer structure to define areas (402) of inconsistency at an internal layer or an interface between adjacent layers. The method includes mapping the areas of inconsistency to finite elements (404) of a finite element model (114) of a nominal of the structure. These finite elements (404) are thereby identified as affected finite elements and include finite elements for the affected internal layer or interface. The method (500) includes producing a reconstructed finite element model of the affected structure (200) from the nominal finite element model (114), and a modified property or state value assigned to respective element datasets of the affected finite elements. The method (500) includes performing a finite element method (FEM) failure analysis (110) of the reconstructed finite element model (116) under a load, which indicates an extent of residual integrity of the affected structure (200). 구조물을 분석하기 위한 방법(500)은 인접한 층들 사이의 경계면 또는 내부층에서 불일치 영역들(402)을 정의하도록 다층 구조물에 대한 NDI(nondestructive inspection) 데이터(112)를 처리하는 것을 포함한다. 본 방법은 구조물의 공칭의 유한 요소 모델(114)의 유한 요소들(404)에 불일치 영역들을 맵핑하는 것을 포함한다. 이러한 유한 요소들(404)은, 이로써, 영향받은 유한 요소들(114)로서 식별되고, 영향받은 내부층 또는 경계면에 대한 유한 요소들(114)을 포함한다. 본 방법(500)은 영향받은 유한 요소들의 각각의 요소 데이터세트들에 할당된 수정된 속성값 또는 상태값, 및 공칭 유한 요소 모델(114)로부터 영향받은 구조물(200)의 재구성된 유한 요소 모델(116)을 생성하는 것을 포함한다. 본 방법(500)은, 영향받은 구조물(200)의 잔여 온전성의 정도를 나타내는, 하중 하에서 재구성된 유한 요소 모델(116)의 유한 요소 방법(FEM) 파손 분석(110)을 수행하는 것을 포함한다.
