“…However, when considering the non-linear and anisotropic behaviour of timber, failure modes are not readily available. Failure criteria such as those in the works of Tsai-Wu [40] and Hashin [41][42][43][44][45] are commonly used to develop composite elements, which can be used to model a GFRP pultruded beam. Hill's [46] anisotropic plasticity-based model has been used to varying levels of success in the FEM of timber.…”

Timber structural members have been widely adopted and used in construction due to their inherent characteristics. The main objective of this work is to assess the performance of timber beams with GFRP pultruded beam reinforcement subjected to flexure. A finite element model (FEM) using ABAQUS FEM software is developed, aiming to provide a benchmark modelling procedure. The modelling method considers the fundamental role of the connections among timber beams, the reinforcing GFRP pultruded profile (adhesive and screw connections), and the grain direction in the timber. To understand the influence of the grain direction, different angles of deviations between the longitudinal direction (along the grain) and the beam axis are considered. The robustness of the developed FEM procedure is validated by the experimental results of timber beams with and without GFRP pultruded reinforcement under flexure. It is demonstrated that the angle of deviation (grain deviation) produces high reductions in the strength of unreinforced timber beams. However, this effect is minimal for GFRP-reinforced timber beams. The experimentally derived benchmark FEM procedure can be used as a computational tool for timber beams with GFRP pultruded reinforcement to capture the capacity, failure mode, and load–displacement response.

“…The estimated stiffness coefficient can be used for the 2D model of the shell segment flanges connection with the same ply sequence of the lamina. In the other study, Klastorny et al [30] developed a numerical model of static process GFRP laminates, including the progressive failure. The mixed sequence layers of laminate with E-glass chopped strand mat and woven roving were examined.…”

Composite material is a well-known structural material which is increasingly adopted as an engineering structure material. Glass fiber reinforced polymer offers the lightweight and high strength characteristics that is required for the modern industry, such as aviation, automotive, wind power, and marine technology. One of the important mechanical characteristics of the composite materials are the tensile properties, because it is well known as the material strength. Therefore, the investigation of mechanical response on the glass fiber reinforced polymer (GFRP) tensile test using numerical analysis is important for the estimation of structural response of the GFRP complex structure, such as boat construction. The objective of this research is to assess and estimate the mechanical response of the GFRP composite material subjected to tension load using finite element method. The linear transversely isotropic model is developed to estimate the unidirectional glass fiber GFRP with the configuration of fiber orientation angles of 0°, 30°, 45°, 60° and 90°. The results show that FE simulation are capable to detect the specimen response during the tensile test. The maximum discrepancy of the estimated stress strain diagram is about 16.5% to 32% compared to experimental data. The larger orientation angle has shown the larger discrepancy value. It is found that the increment of discrepancy value is generated by the nonlinearity behavior of the material due to the domination of polymer material behavior on the large orientation angle. Otherwise, the FE models have estimated accurately the ultimate strength, maximum displacement and fracture load. It can be concluded that the linear transversely isotropic model is adequately accepted as the estimation method of the GFRP composite structure response.

“…2,3 In the field of construction structure, 4,5 the FE model of the thinwalled cold-formed circular hollow sections (CHS) was updated by analyzing the results from the eight different CHS tests conducted by Elchalakani et al, 6 while the validation of the FE model of the steel-concretesteel (SCS) sandwich beams was carried out based on the load-central deflection curves, ultimate strength, and failure modes of the specimens. In the field of material structure, the mechanical behavior of E-glass/ epoxy tube predicted by its thick shell FE model was compared successfully with the experimental results from a series of biaxial static tests, 7 the numerical model of GFRP laminate, recommended in engineering calculations, was determined based on the standard 3point bending test of a GFRP mixed laminate beam, 8 and an FE model of the sandwich construction for alpine skis was developed and validated to simulate the influence of changes of the ski construction on its bending and torsional stiffness. 9 In the field of biomedical engineering, the FE model of human clavicle, which can predict the structural response and bone fractures, was developed and validated based on the results of quasi-static and three-point bending tests conducted on a male clavicle, 10 while 10 human proximal femurs were tested until complete fracture under one-legged stance quasi-static load to validated the QCT/FE models of the human femur, which can predict hip fracture in more adequate physical terms based on continuum damage mechanics.…”

This article presents an economical and efficient way to assess the structural safety and fatigue reliability of the bolster, a key structure for the metro-train. First, its finite element model was validated based on the comparison between numerical results and experimental data of stresses and displacements recorded during a static test. Then, the fatigue life of the bolster under loading scheme was predicted using Gerber diagram, in which the validated finite element model was applied to determine the weak points, and its structural safety was also evaluated by a full-scale fatigue test and nondestructive test method. Finally, the metro-train bolster was modeled as a series system of weak points, and a new fatigue reliability model for mechanical component derived based on stress-life interference model was used to assess its fatigue reliability under the application of the design passenger number spectra. The results show that not only does this bolster satisfy the structural safety requirement during its service life, but also its fatigue reliability is more than 99.993% after 30-year service under normal atmospheric conditions.
