you have a alloy. it has a 75GPa elastic moduls and it has been determined to have  215MPa of yeild strength. if your material has linear elastic stress-strain, figure out what the modulus of resiliance is for your alloy in J/m^

This is a follow up to my question and the answer you submitted. The equation you used for J is wrong, not sure how you got J=π32×Do4-Di4, the equation should be J=π/2×ro4-ri4 which is J=pi/2(50^4-40^4) = 5.8e+6 mm^4

Calculate the applied shear stress. Given: a = 2 mm, b = 100 mm and G = 25 GPa. Consider a linear elastic behavior. ut of Select one: O t= 750 Mpa 11:05 Type here to search 91% ENG 4/15/

3. Assume the plane stress state: ơ1 = 0, 02 = 20, T12 = 15 (all stresses in ksi). If oz alone is increased until the maximum shear stress t1, in the material reaches ±20 ksi, what is the value of o, at this point? HINT: this is relatively easy to figure out if you construct a Mohr's circle for the initial stress state and then consider what happens if o, is replaced with Ao2 and you solve for A when the maximum shear stress (from the circle geometry) reaches ±20 ksi.

If the constraint for a design requires a minimum stiffness of E=100 GPa and the design objective is to maximize the material index M E/p, which will you choose betwoen titanium alloys and CFRP? Justify your answer.

Calculate the activation energy in J/mol for creep for an alloy having the steady state creep behavior shown in the figure. Use the data taken at stress level of 300MPa and temperature of 650C and 730C. Assume that the stress component n is independent of the temperature.

You compress a cylindrical biological sample with an engineering stress of -1 MPa. The sample is made of an isotropic elastic material with Young's modulus of E = 10 MPa and Poisson's ratio v = 0.3.(a) Calculate the engineering strains in the direction where the stress is applied and the transverse direction.(b) How much elastic strain energy is present in the deformed sample if it has a volume of 10 cm3?(c) The material has a hysteresis of 0.1. How much energy will you be able to recover when the sample is relaxed?(d) Calculate the true stress and true strain in the compressed sample.
