Which statement is not correct for the Tresca criterion? Select one: a. It is also known as “Maximum Shear Stress Criterion”. b. It is suitable for materials with brittle behaviour. c. It does not include the influence of the intermediate principal stress. d. The sharp corners of the failure surface can cause numerical problems.
Mohr-Coulomb failure criterion: ?? = ? ′ + ???′ tan?′ Direct shear tests were conducted on dry soil originally. Since water ingress in the soil would reduce the soil strength. If I repeat the direct shear tests using saturated soil, will the values of ??, c’ and ?′ be different from those obtained from the dry test? If yes, how and why?
A loose sandy soil was tested in a direct shear apparatus. The soil obeys the Mohr-Coulomb failure criterion, c = 0, φ = 30◦.The confining pressure/lesser principal stress is 10 psi. Calculate the deviator stress at failure.

The Tresca and von Mises yield criteria concern the yielding of materials by plastic deformation. Which one of the following statements concerning these criteria is false? Choose one of the following options. Select one or more: Neither criterion is suitable for predicting failure by brittle fracture. The von Mises criterion is less conservative than the Tresca criterion. Both criteria are based on principal stress differences. Neither criterion is suitable for predicting yield under torsional stress. Both criteria are empirical, based...
soil mechanics ***Shear strength-11: Use of the Mohr-Coulomb failure envelope. (Revised Oct-09) Samples have been obtained from both soil strata shown in the figure below. A series of shear strength tests were then performed on both samples and plotted in diagrams below. The e' and ' values obtained from these diagrams are shown in the figure below. Using this data, compute the shear strength on the horizontal and vertical planes at points A, B, and C. Sand and grows KN...
3. Shear Strength a. Plot the effective stress Mohr-Coulomb failure envelope for a soil with c'-500 b. A plane through a sample of this soil has an effective normal stress of c.

Will rate, thank you Assume a plane stress load case for the double lap (double plate) joint for three plates. Plate is sandwiched by Plate 2 and Plate 3. They are joined by a fastener. Assume that Plate 2 and Plate 1 are subjected to axial loads of 10,000 lbs and 12,000 lbs respectively. Furthermore there is an external axial load T of 1000 lbs acting on the fastener The bar has a length of 15 inches, a height of...
