— Poisson s ratio is one of the fundamental characteristics in the material models that are used In engineering practice its values are assumed to be constant in the elastic and in the plastic region In this paper the conventionally used values of this number for steel materials and aluminum alloys are confronted with experimental results By using
Yêu cầu trực tuyến →Poisson s ratio of concrete is the ratio of transverse strain to longitudinal strain in concrete specimen subjected to axial loads The longitudinal strain and vertical strain are produced due to concrete volume reduction under compression load Volume reduction of concrete specimen is the result of crushing small aggregate sizes due to exerted
Yêu cầu trực tuyến →Abstract The action of external forces on an elastic medium sets up opposing forces which resist the displacement of the atoms For small displacements simple relationships between force and deformation exist for polycrystalline quasi isotropic materials
Yêu cầu trực tuyến →— What is Poisson s Ratio Poisson s ratio is a measure of the relative deformation that occurs when a material is subjected to an external force Specifically it describes the ratio between the transverse strain and the axial strain of a material In simpler terms when a material is stretched or compressed along one axis it will tend to
Yêu cầu trực tuyến →— The critical value of Poisson s ratio between brittle and ductile materials can be derived as 2/7 which is verified by experimental data Besides the effect of Poisson s ratio on the fracture loci in stress spaces is studied using unified fracture criterion It is found that the decrease in Poisson s ratio increases the asymmetry of
Yêu cầu trực tuyến →— The principal mechanism of iron ore granulation can be described as the layering of adhering fine particles onto the coarse nuclei particles under the action of water as shown in Fig this mechanism is commonly known as auto layering [5 6] A typical iron ore granule is generally comprised of an inner seed coarse particle which
— Expressions are given for the maximum and minimum values of Poisson s ratio ν for materials with cubic symmetry Values less than −1 occur if and only if the maximum shear modulus is associated Login to your account On the non hookean elastic behavior of iron whiskers at high strain Materials Letters

Yêu cầu trực tuyến →— A clean energy revolution is occurring across the world As iron and steelmaking have a tremendous impact on the amount of CO2 emissions there is an increasing attraction towards improving the green footprint of iron and steel production Among reducing agents hydrogen has shown a great potential to be replaced with fossil
Yêu cầu trực tuyến →— In metallic glasses a high Poisson s ratio often corresponds to a large plasticity and ductility Yet the physics underpinning such a connection is still poorly understood Here through finite element simulations we reveal that a high Poisson s ratio could promote the inhomogeneous stress distribution in metallic glasses The
Yêu cầu trực tuyến →— Poisson s Ratio When a material is stretched in one direction it tends to get thinner in the other two directions Restricted Thermal Expansion Force and Stress Stress and force when thermal expansion a pipe beam or similar is restricted Steels Endurance Limits and Fatigue Stress Endurance limits and fatigue stress for steels Stiffness
