Elasticity:It describes the ability of the material to resist the external force and get back to its original shape or size. A high elasticity predicts whether the material is highly elastic or not.Answer and Explanation: The curve of stress versus strain describes the modulus of elasticity. It...
Explain the term Young's modulus, bulk modulus and shear modulus of elasticity.Stress:In physics, stress is a type of physical quantity that defined as the ratio of the internal resistive force to the cross section area of the object. Typically, the standard unit of stress is...
The elastic modulus of electrospun Polyamide (-6.6) nanofibers, which sharply increases in nanofibers with diameters below 500 nm, was measured by both bending and tensile deformation modes. Since the nanofiber surface energy contributes significantly to the elastic modulus measured by bending, but is...
Aluminum and silicon are side-by-side in the periodic table. Which would you expect to have the higher modulus of elasticity (E )? Explain. Why is that in FEA it is preferred to analyze thin structures using shell elements ...
19, one with class I and the other with class II pMHC, based on Kramer’s kinetic theory and accounted for the 3D coarse-grained structures, molecular elasticity, and conformational changes of the TCR–pMHC-I/II complexes. Previously, several models have been developed to describe catch-slip ...

aAn ASTM Type I Portland cement and low calcium class F fly ash are employed in the mix. While excluding coarse aggregates, only silica sand 250 m in grain maximum and 110 m average sizes is used. The PVA fibers are 39 m in diameter, 12 mm in length and have modulus of elasticity ...
Describe the relationship between stress applied to a body and strain deveoped in it using graphical method? View Solution Among solids, liquids and gases, which can have all the three modulus of elasticity? The force F acting on a body moving in a circular path depends on mass of the body...
Ligament failure is a major societal burden causing disability and pain. Failure is caused by trauma at high loading rates. At the macroscopic level increasing strain rates cause an increase in failure stress and modulus, but the mechanism for this strai
