杨氏模量(Young's Modulus)是描述材料在弹性变形阶段内应力与应变关系的物理量,用于衡量材料的刚度或抵抗形变的能力。其值越大,
young modulus的公式 Young modulus,也叫杨氏模量,是材料力学中一个非常重要的概念。它反映了材料在弹性变形阶段,应力与应变之间的线性关系。 杨氏模量的公式是:E = σ / ε。这里的“E”就代表杨氏模量,“σ”表示应力,“ε”表示应变。 咱们先来说说应力“σ”。应力啊,简单来说,就是材料单位面积上所受到的...
young modulus定义杨氏模量(Young's modulus)是描述材料在弹性变形阶段内应力与应变线性关系的物理量,用于衡量材料的刚性。其数值越大,材料抵抗形变的能力越强。以下从多个维度展开具体说明。 1. 基本概念与数学表达 杨氏模量定义为材料在单向受力(拉伸或压缩)时,应力(σ)与应变(ε)的...
杨氏模量(Young's modulus),又称拉伸模量是弹性模量中最常见的一种。杨氏模量衡量的是一个各向同性弹性体的刚度,定义为在胡克定律适用的范围内,单轴应力和单轴形变之间的比(如下图所示)。与弹性模量是包含关系,除了杨氏模量以外,弹性模量还包括体积模量(bulk modulus)和剪切模量(shear modulus)等。
杨氏模量(Young's modulus)是表征在弹性限度内物质材料抗拉或抗压的物理量 它是沿纵向的弹性模量。1807 年因英国医生兼物理学家托马斯 杨(Thomas Young, 1773-1829) 所得到的结果而命名。根据胡克定律在物体的弹性限度内 应力与应变成正比 比值被称为材料的杨氏模量它是表征材料性质的一个物理量仅取决于材料本身的...
