Correction results of double yield model. This image shows the double yield model with the overall trend and peak point of the stress-strain graphs from numerical simulations and laboratory tests being essentially close to each other. The FLAC 3D software was used to model a cylinder with a diameter of 2 m and a height of 4 m at a fixed speed of 2.5 × 10(-1) ,0-5 m/step was applied simultaneously to the top and bottom.
