Question

please help asap and please show all work. thank you!

2) Using data from Table A.1 and A.2, for Aluminum 7075-T6, for given a stress amplitude d+460 MPa a. What are the ELASTIC strain amplitude and the PLASTIC strain amplitude? b. What is the TOTAL strain amplitude? c. Draw accurately to scale, the o-e hysteresis loop for this load cycle. d. To make a comparison, on the same graph draw the standard (monotonic) σ-ε curve out to a maximum of 0.02 strain (the σ-ε curve that would be obtained from a standard tensile test) Sometimes material properties will be somewhat different for cyclic testing compared to a mototonic tensile test. If the cyclic is higher stress at the same strain, we would say the material has become stronger as it is cycled, called "Cyclic Hardening" If the cyclic is lower stress at the same strain, the material has become weaker as it is cycled, called "Cyclic Softening". Which type of material is 7075-T6 aluminum. e.

table 1 data for 7075-T6 below

table 2 data for 7075-T6 below

i added the tables. they correspond within the pictures
