源自拉丁语 'flectere'(弯曲)与后缀 '-ural'(关于...的),17世纪进入工程术语体系。
❶ 与弯曲或挠曲相关的,指物体在受力时发生弯曲的特性或现象。常用于工程、材料科学等领域。
“The flexural strength of the beam was tested under various loads.”
(在不同载荷下测试了梁的抗弯强度。)
“Flexural cracks appeared on the concrete slab after prolonged stress.”
(长期受力后,混凝土板上出现了弯曲裂缝。)
flexural strength — 抗弯强度,指材料在弯曲负荷作用下抵抗断裂的能力,是工程设计中关键参数。
“The flexural strength of this alloy exceeds traditional steel by 30%.”
(这种合金的抗弯强度比传统钢材高出30%。)
flexural rigidity — 抗弯刚度,描述结构件抵抗弯曲变形的能力,计算公式包含弹性模量和截面惯性矩。
“Increasing the beam's thickness improves its flexural rigidity significantly.”
(增加梁的厚度可显著提高其抗弯刚度。)
