On the singular configurations of statically determinate structures

International Journal of Mechanical Sciences, 1965
Abstract This paper shows how singular configurations of statically determinate plane structures can be determined. When the structure is a linkage, such configurations entail degrees of freedom “in the small”, which make it act as a mechanism for infinitesimal motions.

Local Analysis of Singular Configurations of Open and Closed Loop Manipulators

Multibody System Dynamics, 2002
The author presents a general approach to local analysis of singular configurations of both serial and parallel manipulators. It is shown that the maximum rank deficiency of the manipulator Jacobian never has to exceed 4. Singular configurations are classified with respect to active and passive joints.

High-energy behaviour of feynman integrals involving singular configurations

Il Nuovo Cimento, 1964
The high-energy asymptotic behaviour of Feynman diagrams containing certain singular configurations is investigated. The leading contributions are factorized and summed to give Regge-pole terms. A new feature of the discussion is that it is sometimes necessary to scale disconnected sets of lines in addition to the usual connected sets.

On Closure Modes and Singular Configurations of Kinematic Chains

2002
Certain singular configurations of linkages characterised by inactive free- doms or increased mobility are well documented. Less widely known is the fact that the closure modes of a kinematic chain can give rise to various degrees of mobility. These issues are sometimes interwoven as a consequence of simultaneities of special positions and accompanying
