Abstract: A rate‐independent elastoplasticity constitutive model is developed to account for various factors, such as friction, stress path and history, and induced and initial anisotropy in the response of geological materials. A ...

Abstract: The intakes of modern aircraft are subjected to ever-increasing demands in their performance. Particularly, they are expected to carry out diffusion with the highest isentropic efficiency while subjected to aggressive ...

Abstract: The combined-cycle cogeneration facility on the central campus of Texas A&M University was analyzed for its present performance and an optimized mode of operation. The analysis was carried ...

Abstract: National energy security concerns related to liquid transportation fuels have revived interests in alternative liquid fuel sources. Coal-to-fuel technologies feature high efficiency energy conversion ...

Abstract: A simplified approach for the nonassociative behavior of granular (geological) materials is proposed. The basic concept is that the plastic potential can be obtained by controlling or correcting the yield function used for ...

Abstract: The objective of this study was to compare the kinematics of the head-neck, torso, pelvis, and lower extremities and document injuries and their patterns to small female occupants in frontal impacts with upright and reclined ...

Abstract: Anthropometric test devices (ATDs) such as the Hybrid III dummy have been widely used in automotive crash tests to evaluate the risks of injury at different body regions. In recent years, researchers have started using ...

Abstract: PNNL, under direction from DOE, conducted a screening analysis to determine the energy savings potential from the efficiency levels for commercial HVAC and water-heating equipment listed in ...

Abstract: Thermal energy storage can help cogeneration meet the energy generation challenges of the 21st century by increasing the flexibility and performance of cogeneration facilities. Thermal energy ...
