this paper deals with three-dimensional evaluation of the slopes on the basis of limit analysis. an upper-bound technique of limit analysis is used in this paper to determine either the bearing capacity of a shallow foundation near a slope or the safety factor of the slope. the theorems of limit analysis (upper and lower bound) provide a powerful tool for solving problems in which limit loads n...

The present study is devoted to investigation of spur gears with a conchoidal path contact and convex-convex between teeth. load capacity energy efficiency were evaluated using both theoretical experimental approaches. analysis showed that the gear pairs are 5–21% stronger in terms stress have similar as compared involute same configuration. Experiments conducted on test rig. Its was determined...
