Plane Shearing

The total stress consists of the symmetrical stress and asymmetrical stress, and the latter is connected to the couple stresses. A linear constitutive relation is established between the couple stresses and curvature tensor, three material parameters including the rotational modulus are involved in the generalized linear elasticity. A numerical analysis with the finite element method has been accomplished on the scale effect of copper in simple plane shearing. It is shown that a sharp drop of the stress symmetry occurs when the copper structure scale varies from some 1mm to 0.1mm in the example. When we analyze the physical and mechanical properties of cooper structure under micro size scales, the generalized linear elasticity should be used, and the asymmetrical feature of stress tensor must be considered.

Better Than

In order to better understand the distribution of cell traction forces generated by rapidly locomoting cells, we have applied a mathematical analysis to our modified silicone rubber traction assay, based on the plane stress Green’s function of linear elasticity. To achieve this, we made crosslinked silicone rubber films into which we incorporated many more latex beads than previously possible (Figs. 1 and 6), using a modified airbrush. These films could be deformed by fish keratocytes, were virtually drift-free, and showed better than a 90% elastic recovery to micromanipulation (data not shown). Video images of cells locomoting on these films were recorded. From a pair of images representing the undisturbed and stressed states of the film, we recorded the cell’s outline and the associated displacements of bead centroids using Image-1 (Fig. 1). Next, using our own software, a mesh of quadrilaterals was plotted (Fig. 2) to represent the cell outline and to superimpose on the outline a traction density distribution. The net displacement of each bead in the film was calculated from centroid data and displayed with the mesh outline (Fig. 3).
