Dynamic plastic deformation of a free ring subjected to a point load
The permanent deformation of a rigid perfectly-plastic unsupported thin ring subjected to a concentrated time-dependent force acting along a diameter is calculated. The analysis is developed for a force pulse of arbitrary ...
Object-oriented implementation of the Galerkin finite element method and its application to the numerical study of natural convective flows in enclosures
Using object-oriented programming (OOP) techniques and philosophies, a collection of C++ tools for the rapid development of finite element applications has been created. The Object-Oriented Finite Element Analysis (OOFEA) ...
Design of a harmonic drive test apparatus for data acquisition and control
Harmonic drive gear reducers were developed during the mid-1950's and are used in many industrial and military applications. The harmonic drive is a compact, "in-line" gear reducer capable of producing reduction ratios of ...
Mathematical programming problems of quasi-steady flight mechanics
This thesis deals with mathematical programming problems of flight mechanics of a jet aircraft. The aircraft is assumed to be in quasi-steady flight. Different flight phases are considered here; they cover rectilinear level ...
Analysis and control of kinematic error in harmonic gear drive mechanisms
Harmonic gear drives have found increasing application in high performance and precision servomechanisms due to their attractive physical and dynamic properties. However all harmonic gear drives exhibit undesireable nonlinear ...
