Correlation between the Weld Residual Stresses and its Tensile and Impact Strength
In this study, the tensile strength, impact strength, and the hardness of the weld are determined. A criterion is proposed for describing the effect of residual stress on the weld mechanical properties. Dimensionless parameters such as Rya (the average of residual stress over the material yield strength), Rym (the maximum residual stress over the material yield strength), ...
متن کاملNonlinear behaviors of a comb drive actuator under electrically induced tensile and compressive stresses
A theory with experimental verifications has been developed to investigate the nonlinear behavior of comb drive actuators under applied external electrical potential and Joule heating effects. The nonlinear behavior originates from coupled effects of the beam structure under applied electrical potential with electrostatically induced tensile stress and thermally induced compressive stress. Deta...
متن کاملMeasurement of Compressive and Tensile Strength of Ice-silicate Mixtures
Introduction: Understanding the impact process of ice-silicate mixtures is of importance, because water ices exist mostly in a variety of forms of mixtures with silicate or some other components (e.g. ammonia) in the solar system. Decrease of crater volume with increasing silicate content was observed in our previous impact cratering experiments of ice-silicate mixture targets performed using a...
متن کاملCompressive and diametral tensile strength of glass ionomer cements.
The aim of this study was to compare, in different periods of time, the compressive and diametral tensile strength of a traditional high viscous glass ionomer cement: Fuji IX (GC Corporation), with two new Brazilian GIC's: Vitro-Molar (DFL) and Bioglass R (Biodinamica), all indicated for the Atraumatic Restorative Treatment (ART) technique. Fifteen disk specimens (6.0mm diameter x 3.0mm height)...
متن کاملOn Applicability of Some Indirect Tests for Estimation of Tensile Strength of Anisotropic Rocks
The tensile strength of rocks plays a noteworthy role in their failure mechanism, and its determination can be beneficial in optimizing the design of the rock structures. Schistose rocks due to their inherent anisotropy in different foliation directions show a diverse strength at each direction. The purpose of this work was to compare and assess the tensile strength of phyllite, which was obtai...
