TALK=T;RUN(1,1) DISPLAY Experiment Q1 ==> VR A rectangular plate of dimensions LX * LY is * held fixed along its north and west edges * subjected to uniform tension along its south edge * allowed to contract freely along its east edge * in case 1 (plane stress) allowed to contract freely in the z-direction * in case 2 (plane strain) prevented from contracting in the z-direction. The distributions of displacement in the xy plane are computed, and also the corresponding stresses and strains in all three directions. A uniform cartesian grid is used. The computed results are compared with the analytically-derived values. Cases 3 and 4 represent the same situation but with then lower-IY part of the plate being composed of a different material from the uper part. This material has 10 times the compressibility of the first material. In case 3, the poisson's ratio is one tenth that of the first material, so that the lateral extension remains the same, and the solution remains one-dimensional. In case 4 the poisson's ratio is the same as that of the first material; so the lateral extensions differ, and the solution becomes two-dimensional. One-dimensionality can however be restored by making LX much smaller than LY, for example by moving two spaces to the left (and so activating) the line LX=LY/100 below.
