Stress/Strain Relationships Flashcards
1
Q
What occurs due to Poisson’s Effect?
A
According to Poisson’s effect, as we apply forces in the x direction, we will have a force acting in the y direction (Due to necking)
2
Q
How do shear stresses impact materials?
A
They will only change the angles of the shapes, so a square can become a rhombus
3
Q
What occurs to a material when we apply normal forces
A
The dimensions of the shape will extend
4
Q
What is the magnitude of the shear stresses when we have principle stresses?
A
Zero
5
Q
What directions would the maximum shear stress occur?
A
45 degrees relative to the principle axis
6
Q
What is the formula between the Shear Modulus (G) and the Elastic Modulus (E)
A
G = E / (2 * (1+v))
- G = Shear Modulus
- E = Elastic Modulus
- v = Poisson Ratio
