... of the statically admissible solution, where distribution of stress satisfies to the equilibrium equations and strength conditions. O-procedure is an optimization process to get the most favorable stress distribution for providing the maximal pressure. It allows to explicitly account for the variable geometrical...

... not change with the flow rate, which means the flow rate from 90 L/h to 160 L/h is the optimal operating range of this valve. The nonlinear characteristics are mainly caused by the extra hydraulic force produced on the diaphragm in the middle chamber. In order to improve the characteristic of the valve...

.... 30 01 2012 10 05 2012 The paper presents the optimization of toroidal shell cross-sections under internal pressure. The wall thickness distribution along a circular centerline is derived in an analytical form. In membrane solution, this cross-section gives a constant Mises stress all...

...Matthew J. Vick; Kurt Gramoll In this research, an analysis technique is developed to model orthotropic composite toroids and optimize the fiber layup, accounting for the natural variation in thickness due to fiber stacking. The behavior of toroids is difficult to model using membrane shell...

...Yuan Mao Huang; San Nan Tsay This study presents the mechanical efficiency optimization of a sliding vane rotary compressor by using genetic algorithms. Relevant air properties, volume segments, vane loadings and stresses, friction forces, compression power, and power loss are calculated...

...Jagadeep Thota; Mohamed B. Trabia; Brendan J. O’Toole; Ashok K. Ayyaswamy This paper proposes an optimization technique for increasing the structural integrity of a light-weight composite blast containment vessel. The vessel is cylindrical with two hemispherical ends. It has a steel liner...
