摘要：
In stress analysis work a grid system may be affixed to a sheet of metal or other object that undergoes distortion or deformation due to a force being applied thereto. The present grid system of circles and squares (or rectangles) enables easy measurement of maximum and minimum strains and their respective directions and reduces computation time in stress analysis work.
