Opis

Strength of materials problems have been classified into determinate and indeterminate problems. Determinate analysis primarily based on the equilibrium concept is well understood. Solutions of indeterminate problems required additional compatibility conditions, and its comprehension was not exclusive. A solution to indeterminate problem is generated by manipulating the equilibrium concept, either by rewriting in the displacement variables or through the cutting and closing gap technique of the redundant force method. Compatibility improvisation has made analysis cumbersome. The author has researched and understood the compatibility theory. Solutions can be generated with equal emphasis on the equilibrium and compatibility concepts. This technique is called the Integrated Force Method (IFM).IFM equations are manipulated to obtain the Dual Integrated Force Method (IFMD). The subject is introduced through response variables: force, deformation, displacement; and underlying concepts: equilibrium equation, force deformation relation, deformation displacement relation, and compatibility condition. Mechanical load, temperature variation, and support settling are equally emphasized.

O autorze

Began career in 1972, as the Chief of Optimization Group, in the Indian Space Agency, India, following graduation from the Case Western Reserve University, USA. The INAST-1 satellite and its earth-station were the major projects that I handled. Returned to Glenn Research Center, NASA in 1988. Solid mechanics and optimization are my expertise.
