Lab 3: Flexural Deformation Flashcards
1
Q
How do the tensile strength and fracture strengths compare in a brittle material?
A
They’re usually the same
2
Q
How do the tensile strength and fracture strengths compare in a ductile material?
A
The tensile strength is greater than the fracture strength
3
Q
Modulus of Rupture
A
Also known as the flexural strength: stress to fracture a specimen in a bending test
4
Q
Flexural Strength
A
The stress to fracture a specimen in a bending test
5
Q
Flexural Modulus
A
The modulus of elasticity from a bend test.
This gives the slope of the stress-deflection curve.
6
Q
What factors affect yield stress?
GS
PP
A
Grain size and presence of precipitate particles
7
Q
What factors don’t affect yield stress?
SG
LR
DM
TS
A
Sample geometry, lattice resistance, dislocation movement and tensile strength
