Multiscale damage analysis of engineering structures from material level to structural level: a systematic review

International Journal of Structural Integrity, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 27, 2025

Purpose Damage of engineering structures is a nonlinear evolutionary process that spans across both material and structural levels, from mesoscale to macroscale. This paper aims provide comprehensive review damage analysis methods at the levels. Design/methodology/approach study provides an overview multiscale structures, including its definition significance. Current status levels investigated, by reviewing models prediction single-scale perspectives. The discussion includes model-based simulation approaches data-driven techniques, emphasizing their roles applications. Finally, summarize main findings discuss potential future research directions in this field. Findings In level, primarily focuses on degradation properties macroscale using continuum mechanics (CDM). contrast, mesoscale, involves analyzing behavior meso-structural domain, focusing defects like microcracks void growth. structural-level analysis, typically divided into component scales. scale examines progression individual elements, such as beams columns, often detailed finite element or models. evaluates global entire structure, simplified beam shell elements. Originality/value To achieve realistic simulations, it essential include many details possible. However, results significant computational demands. balance accuracy efficiency, are employed. These categorized hierarchical approaches, where different scales processed sequentially, concurrent multiple solved simultaneously capture complex interactions
