Elastic-Plastic Analysis Of Axisymmetrically Loaded Isotropic Circular And Annular Plates Undergoing Large Deflections, Aiman Raji Akileh
Elastic-Plastic Analysis Of Axisymmetrically Loaded Isotropic Circular And Annular Plates Undergoing Large Deflections, Aiman Raji Akileh
Dissertations and Theses
The concept of load analogy is used in the elastic and elastic-plastic analysis of isotropic circular and annular plates undergoing moderately large deflection. The effects of the nonlinear terms of lateral displacement and the plastic strains are considered as additional fictitious lateral loads, edge moments, and in-plane forces acting on the plate. The solution of an elastic or elastic-plastic Von Karman type plate is hence reduced to a set of two equivalent elastic plate problems with small displacements, namely, a plane problem in elasticity and a linear elastic plate bending problem. The method of finite element is employed to solve …
Analysis And Prediction Of The Water Temperature Of The Mckenzie River, Oregon Using The Equilibrium Temperature Approach, R. Peder Hansen
Analysis And Prediction Of The Water Temperature Of The Mckenzie River, Oregon Using The Equilibrium Temperature Approach, R. Peder Hansen
Dissertations and Theses
A one dimensional, steady flow, unsteady temperature model is used to evaluate the effects of two U.S. Army Corps of Engineers (COE) dams and resulting reservoirs on hourly water temperatures of the mainstem McKenzie River from Delta Park (RM 62.1) to Leaburg Dam (RM 38.8). Both COE projects are on tributaries to the McKenzie River and at present have only bottom withdrawl capabilities.
Water temperatures were simulated using the equilibrium temperature approach with air temperature used to estimate equilibrium temperature and also using computed hourly equilibrium temperature. Results obtained using computed equilibrium temperatures were less satisfactory than results using air …
Post-Buckled Performance Of Partially Restrained And Intermediately Supported Steel Angles, Perumal Radhakrishnan
Post-Buckled Performance Of Partially Restrained And Intermediately Supported Steel Angles, Perumal Radhakrishnan
Dissertations and Theses
The post-buckled performance of cross-braced single angles was experimentally determined. The results of this study will be used by the Bonneville Power Administration for the analysis of member performance in transmission towers.
