x-100 steel is one of the most recently developed materials for production of gas transportation pipelines. this material is severely anisotropic. smooth and notched round bars with different notch radius and flat notched specimens with different notch radius and notch depth in tension are tested to characterize the failure of this material under quasi-static loading condition. triaxiality fact...

Bilateral lesions of the basolateral amygdala caused facilitation of instrumental alimentary conditioned reflexes while bilateral cortico-medial amygdala damage produced inhibition of conditioned responses. The most rapid learning was in rats after basolateral lesions whereas the cortico-medial rats required more trials to criterion than controls. In basolateral rats the largest number of inter...

The cemented filling body is taken as the object of this study, whose nonlinear dynamic characteristics of damage and instability are researched by virtue of acoustic emission (AE) under uniaxial cyclic loading and unloading test. The results show that there exists similarity in variation trend between correlation dimension and maximum Lyapunov exponent during each loading stage, which also ver...

Damage diagnosis based on global structural vibrations critically depends the sensor layout, in particular when a small number of sensors is used for large structures under unknown excitation. This paper proposes placement strategy that yields an optimized layout with maximum damage detectability selected components. The optimization criterion Fisher information, which quantifies information da...

Three-point bend fracture tests have been conducted at different loading rates with a quadratic martensitic steel. The failure energy has found to increase rate. To get insights in this numerical investigation undertaken strategies using ABAQUS and IMPETUS softwares order address quasi-static dynamic conditions. Simulations were the software carry out comparative analysis of both implicit expli...

Short Fiber Reinforced Composite (SFRC) structures exhibit multiple microstructures (due to material flow during the process). They are generally subjected variable amplitude loadings. In this context, a robust model is needed predict fatigue life as function of microstructure. paper, we propose predictive micromechanical damage-based allowing prediction in case SFRC submitted cyclic loading. A...

HE stage of cell development at the time of irradiation is one of the most Timportant natural conditions that influence radiosensitivity. This relationship has been demonstrated in detail for the various stages of gametogenesis in male Drosophila, but corresponding studies of females have been far less extensive. For establishing a relationship between the maturation of the female reproductive ...

10 This paper addresses the optimal design and planning of sustainable chemical supply 11 chains (SCs) in the presence of uncertainty in the damage model used to evaluate 12 their environmental performance. The environmental damage is assessed through 13 the Eco-indicator 99, which includes recent advances made in Life Cycle Assess14 ment (LCA). The overall problem is formulated as a bi-criteri...
