網頁The Cauchy stress tensor defined previously, related area vectors n to traction vectors in the current state of deformation of a material object. The first and second Piola-Kirchhoff stress tensors extend the concept of “true” and “engineering” stress to the three-dimensional case and operate on area vectors in the undeformed state of the material. 網頁2024年12月16日 · The Stress Tensor Stress is defined as force per unit area. If we take a cube of material and subject it to an arbitrary load we can measure the stress on it in various directions (figure 4). These measurements will form a second rank tensor; the stress tensor. Figure 4
