Utilizing the large static-dynamic triaxial test system, 7 proportional loading biaxial tensile and compressive tests of concrete were conducted. The proportional loading paths are 0 (uniaxial compression), -0.05, -0.1, -0.15, -0.2, -0.25 and ∞ (uniaxial tension). Compressive and tensile strength were measured as well as the strains at two loading directions. Considering the ratio to tension and compression, failure criteria of ordinary concrete under biaxial tension and compression was established, which has a good agreement with test value.

Progressive failure analysis (PFA) is widely used to predict the failure behavior of composite materials. As a structure becomes more complex with discontinuities, prediction of failure becomes more difficult and mesh dependence must be taken into account. In this study, a PFA model was developed using the Hashin failure criterion and crack band model. The failure initiation was evaluated using the Hashin failure criterion. If failure initiation occurred, the damage variables at each failure mode (fiber tension and compression; matrix tension and compression) were calculated according to linear softening degradation and they were then used to derive the damaged stiffness matrix. This matrix reflected a degraded material, and PFA was continued until the damage variables became “1,” implying complete material failure. A series of processes were performed using the finite element method program ABAQUS with a user-defined material subroutine. To evaluate the proposed PFA model, experimental results of open-hole composite laminate tests were compared with the obtained numerical results. The strain behaviors were compared using a digital image correlation system. The obtained numerical results were in good agreement with the experimental ones.

Braided preforms of carbon fiber are under consideration for structural applications because of the potential for automated fabrication and possible improvement in through-the-thickness properties, although some loss of in-plane properties is expected. In the present investigation, the biaxial compressive strength properties of triaxial braided cylinders are measured experimentally, and the effects of four different sets of braid architectures are considered. The results show that fiber direction strain can correlate the results of biaxial tensile and compression failure tests. The braid parameters are found to have an effect on measured strengths, primarily through the introduction of defects into the fiber paths. The axial compression strength was found to be sensitive to waviness in the fiber path that was produced by uneven braiding coverage. Braid direction compression and tension strength is significantly lower than axial strength, and is also affected by braid parameters.
