Draw stress – strain diagram and explain
a- What are the difference between brittle and ductile.
b- What are the difference between engineering and true.
Answers
Answer:
A) Ductility is a measure of how much a material can be reformed before breaking. Brittle materials don't deform much before breaking. The opposite of ductile is brittle. The main difference between ductile and brittle materials is that ductile material are able to be drawn into thin wires whereas, brittle materials are not able to drawn into thin wires.

Answer:
a) Ductility is a measure of how much a material can be deformed before breaking. Deformation occurs when a material's shape changes. ... The opposite of ductile is brittle. Brittle materials don't deform much before breaking.
b)Engineering strain is the amount that a material deforms per unit length in a tensile test. Also known as nominal strain. True strain equals the natural log of the quotient of current length over the original length as given by Eq4.
