Abstract

Analysis of structural integrity is of fundamental importance to ensure safety and reliability of modern engineering structures, such as those in aerospace, UAV or industrial applications. Finite element assessments of stress, strain, and deformation have been performed previously; however, many of these approaches suffer from narrow material coverage, static loading conditions, ideal material geometries, and poor representation of machining-induced surface damage. In this paper, a new structural assessment method using Finite Element Analysis (FEA) is developed and is proposed to overcome these limitations. The proposed approach involves multi-material modelling, dynamic and fatigue loading, defect-sensitive meshing and Multiphysics coupling to include the complex influences governing the structural response of real structures. By directly modelling stress concentrations, fatigue life, and the effects of additive manufacturing imperfection, the framework allows for high-fidelity predictions with less reliance on costly experimental validation. The compatibility of the system with various industrial domains, the ability to scale the technology to complex geometries, and the preparation of certification altogether represent the comprehensive solution for the present structural analysis issue. Experimental verifications and case-studies reveal that the developed method is accurate, robust and practical for further improving structural safety and performance.
