“…Biaxial strength properties in

stress space are obtained by applying periodical boundary conditions to FE model. Details for RVE model, periodical boundary conditions, and loadings can refer to our previous literature [ 21 ].

Determination of the fracture angle and maximum exposure value of extended Puck’s 3D inter-fiber failure (IFF) criterion is of great importance for predicting the failure mechanism of unidirectional fiber-reinforced composites. In this paper, a reliable semi-analytical algorithm (RSAA) is presented for searching fracture angle and corresponding exposure value for the extended Puck’s failure criterion. One hundred million cases are tested for verifying the accuracy of the present and other algorithms on Python using the strength-value-stress-state combinations more universal than those in previous literatures. The reliability of previous algorithms is discussed and counterexamples are provided for illustration. The statistical results show RSAA is adequate for implementation in extended Puck’s criterion and much more reliable than previous algorithms. RSAA can correctly predict the results with a probability of over 99.999%.

The manufacturing process parameters play a critical role in determining the quality of resin‐matrix composite structures. This study aims to investigate the impact of process parameters on void content and identify the stable and minimal void content of nano‐reinforced filament‐wound risers. Fourteen process parameters were initially designed, taking into account winding tension, speed, and curing time, based on the Box–Behnken design method. Subsequently, a void content model was developed using the response surface method, utilizing experimental data. The study further explores the effects of individual and combined process parameters on void content and establishes a stable process window through sensitivity analysis. Finally, the PSO‐GWO algorithm is employed to optimize winding tension, speed, and curing time with the objective of reducing void content. The results of the numerical analysis highlight the significant influence of curing time on void content, and the optimal parametric combination is determined to be 48.4 N winding tension, 12.6 m/min winding speed, and 6.7 h of curing time.Highlights Winding tension and rate have a similar impact on porosity content. Void content sensitivity to tension is affected by feed rate and curing time. The stable process windows are winding tension [28 N, 53 N], feed rate [30%, 78%], and curing time [5.1 h, 8.4 h]. The optimal parameters combination is 48.4 N, 63%, and 6.7 h.

In composite materials, the use of failure criteria is necessary to determine the failure forces. Various failure criteria are known, from the simplest ones that compare individual stresses with the corresponding strength, to more complex ones that take into account the sign and direction of the stress, as well as mutual interactions of the acting stresses. This study investigates the application of the maximum stress, Tsai-Hill, Tsai-Wu, Puck, Hoffman and Hashin criteria to beech plywood made from a series of plies of differently oriented beech veneers. Specimens were cut from the manufactured boards at various angles and loaded by bending to failure. The mechanical properties of the beech veneer were also determined. The specimens were modelled using the finite element method with a composite modulus and considering the different failure criteria where the failure forces were calculated and compared with the measured values. It was found that the calculated forces based on all failure criteria were lower than those measured experimentally. The forces determined using the maximum stress criterion showed the best agreement between the calculated and measured forces.
