In class, we primarily use this element order type: $(4$pts$)$

a$.$ First Order Elements

b$.$ Second Order Elements

c$.$ Third Order Elements

d$.$ Fourth Order Elements

In general, the finer the mesh density, the better the accuracy of the results: $(2$pts$)$

a$.$ True

b$.$ False

The Elastic Modulus $($Young$\text{'}$s Modulus$)$ is defined as $$ divided by $(4$pts$)$

a$.$ Strain, Stress

b$.$ Stress, Force

c$.$ Stress, Strain

d$.$ Force, Area

For a stress$-$strain curve, the area under the curve represents: $(4$pts$)$

a$.$ The amount of cycling a material can endure before fracturing

b$.$ The ultimate tensile strength of a material

c$.$ The endurance limit of a material

d$.$ The amount of energy a material can absorb before fracturing

The Modulus of Elasticity can be defined as: $(4$ pts $)$

a$.$ The slope of the Stress$-$Strain curve in its linear section

b$.$ The slope of the Stress$-$Strain curve in its non$-$linear section

c$.$ A point tangent to the Ultimate Tensile Strength

d$.$ The first inflection point of a Stress$-$Strain curve

A Stress Element $$ : $(4$pts$)$

a$.$ Represents the maximum von Mises stress at any point in a material

b$.$ Represents the state of stress for an element at a particular point in a material

c$.$ Represents where the material is yielding

d$.$ Represents where the material is likely to fail
