An Optimum Stringer for Straight and Curved Stiffened Panels Using X-FEM Techniques
Abstract: In this study, crack growth, modeling and simulation of various stiffened stringers, unstiffened straight and curved cracked panels are presented using commercially available finite element software package. Computation of stresses and convergence of stress intensity factor for single-edge notch specimens computed using finite element method (FEM) and extended finite element method (X-FEM) and compared with analytical solution. X-FEM techniques like cohesive segment method and linear elastic fracture mechanics, using virtual …

Evaluation of Various Numerical Methods in Large Scale FE Simulation Codes for 3D Crack Propagation
Abstract: In this paper, four different numerical methods implemented in the large scale simulation code LS-DYNA are evaluated to determine their abilities and limitations in fracture problems especially 3-d crack propagation problems. Similar formulations are implemented in the code ABAQUS as well. These methods are: Finite Element Method (FEM), Discrete Element Method (DEM), Element Free Galerkin (EFG) method and Extended Finite Element Method (XFEM). Their methodologies are briefly described and several …

Effectiveness of Video-assisted Instruction on Awareness and Attitude regarding Emergency Contraceptives among the Eligible Couples Residing at Loni (Bk)
Abstract: Background: Despite the availability of highly effective method of contraception, many pregnancies are unplanned and unwanted. Such pregnancies can result in abortion and carry an excess risk of morbidity and mortality. The risk of pregnancy with one unprotected act of sexual intercourse can be as high as one in three, depending on the cycle of exposure in relation to ovulation. For the women exposed to unprotected sexual intercourse, e.g. Lack …
