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...
Explain the term Young's modulus, bulk modulus and shear modulus of elasticity. Why are loops provided in pipes that transport liquids through long distances? Can you explain why water flows in a continuous stream down...
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 ...
Figure 1 shows the tensile engineering stress-strain behavior for a steel alloy. Determine: Modulus of elasticity (b) Proportional limit (c) the yield strength at a strain offset of 0.002 Tensile strength Not the question you’re looking for? Post...
made of L2tool steel, which has a modulus of elasticityE =207GPa and a modulus of rigidityG=75GPa. The shaft has a diameter of40mm,and it has fixed ends at A andB. If the shaft is subjected to the torque shown, determine: ...
The failure mode transition depends on where the maximum stress first reaches the failure point.

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
