Abstract

This paper presents an analysis of the deformations in hollow cross-sectional beams made of multilayer glass fiber-reinforced polymer at force application positions. A non-linear numerical a nalysis is conducted on a beam with a rectangular cross-section and familiar dimensions and material characteristics. Three beams with different spans that are all loaded with two concentrated forces are analyzed, where the distance of the forces from the supports is varied. The kneading deformations at the vicinity, where the two concentrated forces are applied, are monitored with regard to force increase. The results are shown in dimensionless diagrams, wherein the ratio of the actual and initial forces is related to the ratio of deformations at the force application points and mid-span.
玻璃纤维增强梁局部捏合的数值模型
本文分析了多层玻璃纤维增强聚合物空心截面梁在受力位置的变形。对一截面为矩形、尺寸和材料特性相近的梁进行了非线性数值分析。本文对三根不同跨度的梁进行了分析,这三根梁都受到两个集中力的作用,其中力与支座的距离是不同的。在附近的揉捏变形,其中两个集中的力量施加,监测有关力的增加。结果显示在无量纲图中,其中实际力和初始力的比值与施力点和跨中变形的比值有关。
