I have a problem and hope you can help me. I have a square base (15cmx15cm). In my test, I measured the strain at 4 points and would now like to know what the strain is at any point on the surface. I have the following points P = (x, y, value): P1 (8.4, 0, 0.0285), P2 (0, 7.5, 0.05738), P3 (15, 7.5, 0.02903), P4 (7.4, 15, 0.04308) Does anyone have a suggestion on how I could implement this in Python? Thanks in advance! Continue reading...
