Quasi-static and dynamic compression and three-point bending tests have been carried out on Strombus gigas (conch) shells. The mechanical response is correlated with its microstructure and damage mechanisms. The mechanical response is found to vary significantly from specimen to specimen and requires the application of Weibull statistics in order to be quantitatively evaluated. The conch exhibi...

The purpose of this paper is to use static and dynamic load tests evaluate the mechanical performance a simply supported skew slab bridge its actual bearing capacity. Firstly, Midas Civil software used for theoretical simulation, secondly, deflection, strain, response key section are studied through tests. Finally, measured values compared analyzed. results show that: under load, relative resid...

The leaf spring is widely used in automobiles and one of the components of suspension system. It needs to have excellent fatigue life. As a general rule, the leaf spring must be regarded as a safety component as failure could lead to severe accidents. The purpose of this paper is to predict the fatigue life of semi-elliptical steel leaf spring along with analytical stress and deflection calcula...

Electric fields are pervasively present in the environment and occur both as a result of man-made activities and through natural occurrence. We have analysed the behaviour of cockroaches to static electric fields and determined the physiological mechanisms that underlie their behavioural responses. The behaviour of animals in response to electric fields was tested using a Y-choice chamber with ...

Abstract This article presents the measurement and analysis of influence velocity on quasi-static deflections industrial manipulators three different manufacturers. Quasi-static deflection refers to end effector position articulated robots during movement at low along a predefined trajectory. Based earlier reported observations by authors, there exists difference in static considering same poin...

In this paper, the effects of initial deflection on static and dynamic behaviors circular capacitive transducers are experimentally investigated. The obtained results in good agreement with numerical simulations. It is shown that has a major impact response resonator by shifting pull-in voltage, its increasing resonance frequency modifying bifurcation topology from softening to hardening behavi...

The fruit fly Drosophila melanogaster responds behaviorally to sound, gravity, and wind. Johnston's organ (JO) at the antennal base serves as a sensory organ in the fruit fly to detect these mechanosensory stimuli. Among the five anatomically defined subgroups of sensory neurons in JO, subgroups A and B detect sound vibrations and subgroups C and E respond to static deflections, such as gravity...
