Calculations: $($For all specimens$)$

Include a table with the load and displacement $($length$)$ readings that were used for the

following calculations $(2$ points$)$:

a$.$ Modulus;

b$.$ Yield strength and yield strain

c$.$ Ultimate tensile strength and strain at UTS

d$.$ Failure strength and failure strain.

Plot engineering stress vs$.$ strain. $(3$ points$)$

Calculate true stress, true strain and determine the values of K and n for the materials Tested.

$(3$ points$)$

Plot true stress vs$.$ true strain. $(3$ points$)$

Find the toughness of the materials tested. $(3$ points$)$

Based on the mechanical behavior exhibited by the materials and their physical

characteristics $($color$/$density$)$ indicate what materials$/$alloys were tested. $(3$ points$)$

Based on the objectives of this lab$/$topic$,$ identify ethical and professional responsibilities that should

be considered in engineering situations to make informed judgments, which must consider the impact of

engineering solutions in global, economic, environmental, and societal contexts. $(1$ point$)$ THE K VALUE FOR ALUMINUM IS $180$ & n$=0\mathrm{.}20$
