Proposals for a Failure Criterion Applicable to Discontinuous Rocks
The existing failure criteria to evaluate discontinuous rocks are predominatly based on the relations between principal stresses at failure. None of the criteria has a direct reference to the magnitude of deformation as a major parameter in rock Several reasons are identified indicating that the selection of peak stress as a major parameter, which is obtained through the evaluation of a failure...
متن کاملNew empirical failure criterion for shale
A new failure criterion was presented to predict the ultimate strength of shale under the triaxial and polyaxial state of stress. A database containing 93 datasets was obtained from the results of the uniaxial, triaxial, polyaxial compressive tests, an indirect tensile test was collected from reliable references, and this test was carried out on the shale samples taken from the southwestern oil...
متن کاملGeneralized energy failure criterion
Discovering a generalized criterion that can predict the mechanical failure of various different structural materials is one of ultimate goals for scientists in both material and mechanics communities. Since the first study on the failure criterion of materials by Galileo, about three centuries have passed. Now we eventually find the "generalized energy criterion", as presented here, which appe...
متن کاملA COMBINATION OF PARTICLE SWARM OPTIMIZATION AND MULTI-CRITERION DECISION-MAKING FOR OPTIMUM DESIGN OF REINFORCED CONCRETE FRAMES
Structural design optimization usually deals with multiple conflicting objectives to obtain the minimum construction cost, minimum weight, and maximum safety of the final design. Therefore, finding the optimum design is hard and time-consuming for such problems. In this paper, we borrow the basic concept of multi-criterion decision-making and combine it with Particle Swarm Optimi...
متن کاملOptimal Sensors Location Using Modal Assurance Criterion in Modal Identification of Concrete Gravity Dams
Determination of the optimal sensors location in order to identify of modal parameters, especially in large structures such as dams, is one of the practical issues, which is widely used in damage detection and structural health monitoring. The main objective of this study is to obtain the most information from the dynamic response in a concrete gravity dam by minimizing the non-diagonal element...
