Abstract: The macrostructure of a granular material is treated as an ensemble of microstates of like spheres where each microstate is identified by a coordination number and a corresponding porosity. The probability of occurrence ...

Abstract: Distortion and residual stresses cause significant problems in the welding of large structures. Prediction of these phenomena would provide substantial assistance to the design and fabrication of ...

Abstract: The majority of structural failures, whether collapse or functional, are attributable to errors in design, construction, or operation. This paper attempts to review selected literature on the subject of errors in structural ...

Abstract: Although rate-change experiments are essential for characterizing rate-dependent flow, certain nonobvious aspects of test machine dynamic response and control system strategies can distort rate-change ...

Abstract: The process of accounting for subjective information, insight, and wisdom in structural engineering decision making is a matter of debate. One effort to include verbal ideas involves the use of the fuzzy set theory. This ...

Abstract: When a sphere is held between parallel flat surfaces by means of a constant clamping pressure and is then subjected to a cyclic tangential displacement parallel to the flats, energy is ...

Abstract: The ability to balance is important to the mobility obtained by legged creatures found in nature, and may someday lead to versatile legged vehicles. In order to study the role of balance in ...
