This document contains abstracts of presentations made at the Work-In-Progress Session of the Army Symposium on Solid Mechanics, 1974. These sessions were comprised of a series of brief presentations and discussions of current (but not necessarily complete) research relating to the theme of the symposium: 'The Role of Mechanics in Design - Structural Joints.' This meeting was held at Bass River (Cape Cod), Massachusetts on 10-12 September 1974. The proceedings of this symposium are published in a companion document, Army Materials and Mechanics Research Center Monograph Series Report, AMMRC MS 74-8 dated September 1974.

In this report we discuss the work performed on the main component of the suspension system, the torsion bars. Torsion bars in the tank are designed to be mainly subjected to torsional loads, however, actual loading is feared to have some other stress components. In the first phase of the failure analysis, a bar which failed in the field was obtained. The examinations performed on the bar were: Magnetic flux examination of both parts of the failed bar, to determine any other cracks; Chemical analysis to evaluate conformity with the standards; Standard charpy specimens, for evaluating transition temperature; Pre-cracked charpy to evaluate fracture toughness; Tension test; Short-rod fracture specimen for evaluating fracture toughness; Rockwell hardness traverse; Fractographic examination of fracture surface, (a) light microscopy SEM, to locate the origin of cracks and the extent of fatigue crack growth, and Metallurgical Examination of Crystalline Structure in the gage and spline area.
