Progressive failure analysis of notched composite plate by utilizing macro mechanics approach

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 623-642 doi: 10.1007/s11709-021-0726-8

Abstract: In this study, gradual and sudden reduction methods were combined to simulate a progressive failure inUsing the presented method, a progressive failure is simulated based on a linear softening law priorto a catastrophic failure, and thereafter, sudden reduction methods are employed for modeling a progressivefailure.The proposed method is intended to predict the first ply failure (FPF), LPF, and dominant failure modes

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 7,   Pages 871-881 doi: 10.1007/s11709-022-0863-8

Abstract: The failure criteria of practical soil mass are very complex, and have significant influence on the safetyThe Coulomb strength criterion and the power-law failure criterion are classically simplified.criterion is better than those of the linear Coulomb criterion and nonlinear power-law criterion.Based on the proposed LSSVM approach to determine the failure criterion, the limit equilibrium methodcriterion-based method and the power-law failure criterion-based method are about 12% and 7%, respectively

Abstract: This study focuses on the bending failure performance of a shield tunnel segment.A full-scale test was conducted to investigate deformation and failure characteristics.During the loading, the bending failure process can be divided into four stages: the elastic stage, workingstage with cracks, failure stage, and ultimate stage.The characteristic loads between contiguous stages are the cracking, failure, and ultimate loads.
