“…In predicting the damage evolution, a number of algorithms that attenuating material stiffness have been proposed. [28][29][30][31] After preliminary comparison, selected criteria and corresponding degradation rules were conducted (Table 2), using Fortran coded subroutine of Abaqus USDFLD. Fiber breakage, matrix crack, shear damage, and interface delamination were considered for composite damage.…”

Tensile experiments were conducted with single-bolted and multi-bolted countersunk composite-metal joints. The finite element models with Hashin criteria and modified Camanho degradation law were developed to predict the bearing load and to simulate the failure behavior. The models were validated with the experimental results, including load-displacement curves and composite damage profiles. Based on the verified models, bolt load distributions of multi-bolted joints were calculated and analyzed before and after damage occurs. Results show that composite damages can change the bolt load distributions to a certain extent, which needs to be considered during the structure design. To adjust the bolt load distribution, the effects of joint variables, including bolt-hole clearance, bolt spacing, countersunk height ratio, and bolt stiffness combination, have been studied. It is found that the increase of the pin clearance around the largest bearing bolt would decrease its corresponding bearing load. The countersunk height ratio affects the bolt load distribution difference that a greater ratio leads to a less difference. The bolt spacing and bolt stiffness can also be used to reduce the bolt load distribution difference with elaborately designed combinations.

“…For G827/5224 the degradation technique proposed by Camanho and Matthews is the most reliable because it includes the ability to adjust the value of the applied degradation factors in each application. Attenuation criteria can be seen in reference [6] .…”

Tensile mechanical behaviors of two kinds composite laminates G803/5224 and G827/5224 specimen after high-speed impact were investigated separately. The influences of open-hole on the specimen’s net tensile strength were analyzed by comparing with standard specimen’s experimental results. An FEM model was established to simulate the damage growth in the laminates. Different equivalent zones were applied to model different velocity impact damages, and different damage criteria and modulus attenuation rules were used for two different ply forms.

“…Because there are the same strength failure characteristics in direction 1 and in direction 2 of bidirectional ply, there are the same stiffness degradation rules in direction 1 and in direction 2 of bidirectional ply. And based on the stiffness degradation rules which from theses [14], the new rules could be developed as shown in Table 3: The failure elements gradually accumulate with the increase of load until the laminates can not support. The final destruction criterion of laminates in thesis [15] is: when the elements with fiber failure extended to the edge of laminates along the direction vertical tensile load, the laminates will fracture, cannot support.…”

According to the structural difference between the unidirectional and the bidirectional laminate ply, the traditional 3-D (three-dimensional) Hashin failure criteria and the corresponding stiffness degradation rules were amended for damage tolerance simulation analysis of plane woven-reinforced laminates. Based on 3-D finite element technique, a secondary development was carried out on ANSYS software platform, a cumulative damage model was established, and the simulation analysis program for damage tolerance analysis of plane woven-reinforced laminates with hole damage was developed by use of APDL (ANSYS Parametric Design Language). In order to study the influence of different hole diameters on damage tolerance of plane woven-reinforced laminates, two kinds of G803/BMP316 plane woven-reinforced laminates with different hole diameters were selected as the analysis and verification object, and residual tensile strength and damage extension process of the damaged laminates were predicted and analyzed in the simulation. The simulations results are close to the experimental results, and visually present the situation of damage extension in each ply. It provides an effective tool for the damage tolerance analysis of plane woven-reinforced laminates with hole damage.
