“…However, this is highly recommendable, as these are materials with a high anisotropy, due to both heterogeneity and to the fused deposition process. Kang et al [112] carried out one of the first biaxial studies on this type of material, specifically testing polyether ether ketone (PEEK) reinforced with short carbon fibre. Through a methodology that combines uniaxial tests with a numerical model that includes anisotropy and plasticity of the material, the researchers determined the stress-strain response of the material subjected to five different stress ratios.…”

The heterogeneity and anisotropy of fibre-reinforced polymer matrix composites results in a highly complex mechanical response and failure under multiaxial loading states. Among the different biaxial testing techniques, tests with cruciform specimens have been a preferred option, although nowadays, they continue to raise a lack of consensus. It is therefore necessary to review the state of the art of this testing methodology applied to fibre-reinforced polymers. In this context, aspects such as the specific constituents, the geometric design of the specimen or the application of different tensile/compressive load ratios must be analysed in detail before being able to establish a suitable testing procedure. In addition, the most significant results obtained in terms of the analytical, numerical and experimental analyses of the biaxial tests with cruciform specimens are collected. Finally, significant modifications proposed in literature are detailed, which can lead to variants or adaptations of the tests with cruciform specimens, increasing their scope.

“…Although many studies have focused on mechanical properties [ 2–11 ] fatigue [ 12–18 ] and damage [ 19–30 ] of ROS composites to some extents, theoretical analysis of their creep behaviors has gained less attention in open literature. Park and Balatinecz [ 31 ] studied empirically the short‐term creep of wood‐fiber reinforced PE composites.…”

The main purpose of this research is to develop a model investigating creep phenomenon in polymeric composites reinforced with randomly oriented short fibers. The creep phenomenon is first analyzed in a representative volume element of a long‐fiber composites at the scale of micro through an implicit approach. Then, creep analysis is performed at laminate level as the macro‐scale analysis. Then, creep response of a quasi‐isotropic laminate is obtained where the outputs of the micro‐scale analysis are fed as input data to the macro‐scale modeling. Laminate analogy is properly integrated with creep modeling technique to obtain the creep behavior of randomly oriented short fiber composites. The results of modeling are compared with published experimental data revealing the proper performance of the developed modeling for both short‐term and long‐term creep phenomena.

“…Finite element approach as a powerful numerical tool [5][6][7] has been frequently used to estimate the mechanical response of SFRPs in a wide range of domains [8][9][10][11][12][13][14][15][16][17]. In this regard, Breuer and Stommel [18] studied the effects of fiber geometry, packing configuration, fiber length and orientation distributions on the elastic response of SFRPs.…”
