Abstract

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.
单向GFRP复合材料拉载力学响应的有限元数值分析
复合材料是一种众所周知的结构材料,作为工程结构材料越来越多地被采用。玻璃纤维增强聚合物提供了现代工业所需的轻质和高强度特性,例如航空,汽车,风力发电和海洋技术。复合材料的重要力学特性之一是拉伸性能,因为它是众所周知的材料强度。因此,利用数值分析方法研究玻璃钢(GFRP)拉伸试验的力学响应对玻璃钢复合结构(如船体结构)的结构响应估计具有重要意义。本研究的目的是利用有限元法评估和估计GFRP复合材料在拉伸载荷作用下的力学响应。建立了纤维取向角为0°、30°、45°、60°和90°的单向玻璃纤维玻璃钢的线性横向各向同性模型。结果表明,有限元模拟能够较好地反映试件在拉伸试验过程中的响应。估计的应力应变图与实验数据的最大差异约为16.5% ~ 32%。取向角越大,差异值越大。结果表明,由于高分子材料的行为在大取向角上占主导地位,导致材料的非线性行为导致了差异值的增加。除此之外,有限元模型可以准确地估算出极限强度、最大位移和断裂载荷。结果表明,线性横向各向同性模型可以作为GFRP复合材料结构响应的估计方法。
