Two-Step Identification Method and Experimental Verification of Weld Damage at Joints in Spatial Grid Structures

open access: yesBuildings, 2023
Welded joints in grid structures are susceptible to damage and destruction when exposed to random excitation. The complexity of the grid structure poses challenges for realizing the damage recognition of welded joints. In this study, a two-step method is

Progressive damage and rupture in polymers

open access: yes, 2017
Progressive damage, which eventually leads to failure, is ubiquitous in biological and synthetic polymers. The simplest case to consider is that of elastomeric materials, which can undergo large reversible deformations with negligible rate dependence. In
