Present study deals with the prediction of crack initiation angle for mixed mode (I/II) fracture using finite element techniques and J-Integral based approach. The FE code ANSYS is used to estimate the stress intensity factor numerically. The estimated values of SIF were incorporated into six different crack initiation angle criteria to predict the crack initiation angle. Single edge crack spec...

One of the most effective parameters in economics of open-pit mines is the pit slope angle, so that the slope angle more than the optimum value increases the probability of a large failure in the pit wall and the slope angle less than the optimum value leads to increasing stripping ratio and reducing net present value of mine. Therefore, in this paper, considering the limit equilibrium methods ...

background: a number of ocular biometric parameters, iris hiotologic and anatomic characters have been suggested as inciting factors for converting patients with narrow angle to angle-closure glaucoma. this study was conducted to determine if there was any goniscopic difference between patients with acute angle-closure glaucoma (aacg) and chronic angle-closure glaucoma (cacg). methods: the stud...
