- Description
- Concern for possible adverse effects of end restraint in triaxial compression testing is almost as old as the technique of conducting such tests. A finite element model is established to study the influence of end restraint effects on drained triaxial strength of soil in this paper. Results from simulations with free ends are compared with those from simulations with restraint ends. The comparison revealed that the obtained shear strengths from simulations with free ends and restraint ends are almost the same for non-dilative soil. With the increase in dilation angle, the relationship between the average deviatoric stress of all of the elements in the specimen and the vertical displacement did not show any change. However, the stress in the specimen with free ends was uniform while the stress in the specimen with fixed ends was not uniform. The investigation shows that the end restraints only influence the stress distribution in the specimen and do not influence the overall behaviour of it for drained triaxial tests.
