In the present research, the mixed-mode fracture mechanics analysis in a plate with central hole under tensile loading is considered. It is assumed that a plate containing two symmetrical hole-edge cracks is bonded with two dissimilar planes. The stress intensity factors at the crack tips are calculated. The problem is modeled in Casca software and this model is analyzed with Franc software. Th...

exogenous enzymes such as xylanase can cause recovery of efficiency in poultry. in this study we investigated the effects of xylanase supplementation on small intestine histomorphometry in broilers chicken. two levels of xylanase supplementation (with or without 0.07% xylanase) was used in 4 treatment groups (two repetitions for each group and 15 chicks per group). after 42 days, 10 chicks from...

the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...
