“…However, for semi-empirical approaches, although the determination of the extent of current damage combines mechanical parameters such as strain, stress and displacement near the damaged zone when calculating damage evolution variables, linear or exponential trends of stiffness degradation must be previously defined. Due to the involvement of mechanical parameters, methods based on fracture energy, which are typical of semi-empirical methods, are now widely employed by researchers for predicting the progressive damage behavior of composite materials [4][5][6][7][17][18][19][20][21][22].…”

“…In addition, Air et al [7] used the Tsai-Wu criteria [8], and Long et al [18] adopted Hashin criteria [9], while Tan et al [6] used modified Puck criteria [13] and Shi et al [19] combined Puck's matrix compression criterion and Hashin's fiber and matrix tensile criteria in their numerical simulations; the damage evolution in all of these studies was controlled by fracture energy-based methods that involve equivalent strain. In other studies, Qiu et al [20], Zhang et al [21], and Caputo et al [22] all chose Hashin criteria [9] and linear damage evolution methods by calculating the equivalent displacement.…”

This study aims to evaluate the applicability of failure criteria and damage evolution methods in the finite element analysis of composite laminates under lowvelocity impact. Implemented by the user-defined VUMAT subroutine in ABAQUS, various progressive damage models are used to predict damage initiation and accumulation in a T700GC/M21 composite laminate. Cohesive elements are inserted between adjacent plies to capture interface delamination. The applicability of damage models is investigated by comparing the global mechanical response and distribution of various damage modes. A new variable, equivalent damage volume, is introduced to quantitatively describe the predicted damage when using different models. The numerical results establish that Hashin and Puck failure criteria generate matrix compression damage in more layers of the composite. Maximum stress and Tsai-Wu criteria are not preferred due to their improper predictions in terms of damage area and permanent deformation of the laminate. As for damage evolution laws, the equivalent strain method provides faster stiffness degradation of the laminate and a smaller area 2 of matrix damage compared with the predictions of the equivalent displacement method.

“…Many studies of ship-bridge collision responses [16,17] and device usage [18,19] have been reported. For example, Qiu et al [20] analyzed an original protective device scheme and proposed structural and material optimization for the protective device [21][22][23].…”

Corrosion deterioration of steel can heavily degrade the performance of marine and offshore structures. A typical steel protective device, which has worked for a dozen years in a river estuary, is selected as the research object. Its current corrosion response is measured on site and its further corrosive response is predicted based on measurement data and the structure's current state. Nonlinear finite element method is utilized to analyze the degradation of the protective device's anti-collision performance. Meanwhile the rubber buffer effect has been investigated for its anti-collision on the protective device. A prediction method is proposed that can accurately forecast degradation of the anti-collision performance of a protective device as time progresses.

“…Much work has focused on improving the poor resistance of laminated composites to impact loading. Qiu et al [16] investigated impact factors including geometry, thickness, stiffness, mass, and impact energies (impact velocities), all of which have remarkable influence on the damage resistance of laminated composites, and design suggestions were proposed.…”
