Since the literature lacks an effective analysis method of collapse mechanisms and optimisation design theory for progressive resistance cable dome structure, a structural performance-based approach was proposed to improve structures in this study. First, dynamic response model structure were analysed after its members removed using Ansys LS-DYNA full equivalent load-based instantaneous unloadi...

In this article, a semi-analytical solution is provided to investigate the free vibration characteristics of rotating truncated conical shells surrounded by Winkler–Pasternak type foundation. It assumed that material shell composed epoxy as matrix and graphene nanoplatelets (GPLs) reinforcement dispersed in both thickness length directions shell. The modeled based on first-order shear deformati...

The use of bedded hoop barns in finishing systems for beef cattle has not been widely researched. In this management system, beef cattle are confined to hoop barns throughout finishing, and bedding is used to absorb animal waste, which results in minimal effluent. The objective of this study was to compare the performance and carcass characteristics of finishing beef steers (n = 1,428) managed ...

Three completely different lines of work have recently led to the conclusion that the magnetorotational instability (MRI) may create a hoop-stress that collimates jets. One argument is based upon consideration that magnetohydrodynamic turbulence, in general, and turbulence driven by the MRI, in particular, is more nearly viscoelastic than it is viscous. Another argument is based upon the disper...

A study was conducted to document the physical environment and growth performance of nursery pigs in hoop structures compared with pigs reared in confinement nurseries. A series of six trials involving a total of 1,440 nursery pigs were conducted at two Iowa State University research farms from December 1999 to August 2000. Regardless of season, the confinement pigs grew faster and consumed mor...

Abstract This paper deals with the boundary force method to determine stress distribution in an infinite plate subjected uni-axial tension having elliptical or circular hole. The elasticity solution for a point is used as fundamental solution. conditions are satisfied terms of resultant forces. Stress obtained by validated against results from analytical equations. Traction free condition weakl...

AIMS The aim of this study is to investigate how the myocardial bridge oppression affects the hoop stress of mural coronary artery. METHODS The "myocardial bridge - coronary artery" simulative device records the hoop stress which is changed by adjusting the external pressure of the simulated coronary artery and the oppression degree of the respectively. RESULTS Simulation experiment in vitr...
