two cylindrical specimens A and B of a soil were loaded as follows. Both specimen were isotropically loaded by a stress of 200 kpa under drained conditions. Subsequently, the radial stress applied on specimen A was held constant and the axial stress was incrementally increased to 440 kpa under undrained conditions. The axial stress on specimen B was held constant and the radial stress was incrementally reduced to 50 kpa under drained conditions. plot the total and effective stress paths for each specimen assuming the soil is linear. isotropic. elastic material.calculate the maximum excess pore water pressure in specimen A.
