Evaluation of Damage Distribution in Elements of Dual Frames
Researches show that the strength criterion is inadequate for design of structures against seismic loads. Since structures yield and experience plastic deformation under strong ground motion, considering structural damage with inelastic behavior may be a considerable criterion for design and control of the structures.In this paper, three steel structures with dual system consisting of intermedi...
متن کاملEvaluation of Ductile Damage Criteria in Hot Forming Processes
The process of ductile fracture which occurs due to the accumulation, growth and combination of defects or cracks of material is called ductile damage. Failure in materials can be predicted, using damage mechanics and damage criteria. On the other hand, most of the materials depended to the manufacturing process, are formed in warm or hot conditions so that; the temperature also affects on the ...
متن کاملTo Crash or Not To Crash: Efficient Modeling of Fail-Stop Faults
A commonly used approach in practical verification is to verify a simplified model of the system rather than the system itself, which would entail infeasible verification complexity. This paper introduces a model for efficient model checking of message-passing systems with crash faults. The key to the achieved efficiency is the intuition that the event of process crash can be omitted in the mod...
متن کاملDual Criteria Decisions
Abstract. The most popular models of decision making use a single criterion to evaluate projects or lotteries. However, decision makers may actually consider multiple criteria when evaluating projects. We consider a dual criteria model from psychology. This model integrates the familiar tradeoffs between risk and utility that economists traditionally assume, allowance for rank-dependent decisio...
متن کاملSecondary collisions revisited: real-world crash data and relationship to crash test criteria.
OBJECTIVES Previous research conducted in the late 1980s suggested that vehicle impacts following an initial barrier collision increase severe occupant injury risk. Now over 25 years old, the data are no longer representative of the currently installed barriers or the present US vehicle fleet. The purpose of this study is to provide a present-day assessment of secondary collisions and to determ...
