Strain Elastic-plastic Theories
In a unified approach, the virtual work equations in rate form and in incremental forms are derived rigorously for elastic-plastic continuum subjected to large strains. T h e finite element p r d u r e s for the analyses of clastic-plastic solid b a d on Lee’s theory and the Green-Naghdi theory arc presented. Also, i t i s shown that transformations can be performed among the Eulerian, the Tota...
متن کاملOptimum Design of Hydraulic Excavator
Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". In this paper the hydraulic shovel excavator is analyzed through the D-H method. The shovel working device with the bucket capacity of 36m3 is optimized. The determination of the objective function, variables and constraints are described in ...
متن کاملAnalysis of Rotational Column with Plastic Hinge
Michael Long, Rice University; Corey Bergad, Bates College; EERC Name: MCEER Host Institution: SUNY at Buffalo Faculty Advisor: Dr. Andrei Reinhorn ________________________________________________________________________ Abstract: A plastic hinge is a type of energy dampening device allowing plastic rotation of an otherwise rigid column connection. This device is composed of a weakened portion ...
متن کاملElastic-Plastic Invariant of Localized Deformation Autowaves
The parameters of localization patterns emerging at the linear stage of work hardening are discussed in the frame of autowave concept. The stress-strain diagrams have been plotted for the test samples of metals exposed to active loading. It is found that the product of phase autowave velocity and length has the same order of magnitude as the product of elastic wave rate and the lattice constant...
