“…Firstly, the constant-amplitude fatigue tests for undamaged and post-impact laminate specimens of [(45/-45)/(0/90)] 3s were conducted under tension-tension (T-T) and compression-compression (C-C) cyclic loading at the stress ratios of 0.05 and 10, respectively. The anti-buckling fixture was used to avoid the global buckling of the specimen under C-C loading [34] . For each specimen type, at least four groups of fatigue tests were conducted under different stress levels to achieve four target fatigue lives.…”

“…In the LVI progressive damage simulation, the failure mode of interlaminar delamination is characterised by the ABAQUS built-in cohesive zone model, in which maximum stress criterion and B-K rule are generally used for identifying delamination initiation and evolution [34] . Other failure modes identification and relevant material property degradation are realised in progressive damage algorithm, which is written in the VUMAT subroutine.…”

“…Ply discount model based on stiffness reduction seems simple but effective to define the progressive degradation in mechanical properties of damaged composite material, 26,27 here the reduction of stiffness is dependent on the individual failure mode. In other words, once element reaches failure, the stiffness matrix C of material is degraded according to ply discount model.…”

This paper outlines progressive damage characteristics of screwed single-lap CFRPI-metal joints subjected to tensile loading at RT (room temperature) and 350°C. Quasi-static tensile tests were performed on screwed single-lap CCF300/AC721-30CrMnSiA joint at RT and 350°C, and the load versus displacement curve, strength and stiffness of joint were gauged and discussed. With due consideration of thermal-mechanical interaction and complex failure mechanism, a modified progressive damage model (PDM) based on the mixed failure criterion was devised to simulate progressive damage characteristics of screwed single-lap CCF300/AC721-30CrMnSiA joint, and simulations correlate well with experiments. By using the PDM, the effects of geometry dimensions on mechanical characteristics of screwed single-lap CCF300/AC721-30CrMnSiA joint were analyzed and discussed.

“…With the advancement in computing capability and the wide application of the finite element method (FEM), the theory of progressive damage analysis (PDA) for structural failure analysis has become a research hotspot in recent decades. [13][14][15][16][17][18][19][20] PDA methods can be generally divided into three primary categories. The earliest developed method is the crack propagation model based on the theory of fracture mechanics, which mainly discusses the influence of interlaminar and intralaminar crack growth on the residual mechanical properties.…”

Complex failure modes of carbon fiber reinforced polymer (CFRP) composites create significant challenges for CFRP components' progressive damage analysis (PDA). Though important in PDA, the phenomenological strain‐softening model (SSM) for characterizing the degradation behavior in the fiber‐parallel direction (dominated by fiber breakage) of CFRP is difficult to be constructed by current approaches due to the poor toughness of carbon fibers. The work aims to obtain a refined SSM of plain woven CFRP composites through experimental methods and apply it to the PDA of corresponding components. A novel phenomenological cyclic‐loading‐based strain‐softening model (CLSSM) was proposed based on the theory of equivalent dissipation energy during static and cyclic loading. Firstly, the release behavior of dissipation energy during the cyclic loading process was researched. Secondly, a newly designed search algorithm taking degraded mechanical properties during cyclic loading as input and taking the static strain‐softening curve as output was utilized to build up CLSSM. Thirdly, a three‐point bending test was conducted and a corresponding numerical model was constructed for comparison to verify the proposed model. The entire framework is highly programmatic, and results show that CLSSM is fast for characterizing the strain‐softening behavior, and effectively simulates the progressive failure process of CFRP components.
