The material has to stretch (strain) first before it breaks. For ductile materials, when stretch reaches a certain point it permanently deforms (yield) and continues to carry load until it then breaks as load increases.
For brittle materials like glass which do not permanently deform thay simply break without yield.

Is tensile strength of cold rolled steel is greater than yield stress?
For ductile materials, the yield stress is always lower than the tensile strength of the material. For brittle material they can usually be considered the same point. Steel is generally considered ductile.
What is the yield strength of cast iron?
For the usual run of cast iron, The yield stength almost coincides with its fracture strength - cast iron is very brittle and fractures at usually more than 20000 pounds per square inch. DUCTILE cast iron is one of the several irons that DO yield before cracking.
What is the yield strength of plywood?
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
What is the Significance of recrystallization temperature in metalworking?
Recrystallization temperature in metal working can be defined as the temperature at which the plastic deformation takes place perfectly. The stresses induced during the process is are grater than the yield strength and less than the fracture strength.
What is yield strength and tensile strength of 20c8 cast steel?
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
Which one is greater yield strength or breaking strength?
The breaking strength is always greater than the yield strength.

Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
Can the Yield strength of steel ever be greater than the Ultimate tensile strength?
The yield strength is reached when the material becomes non - linear ( that is non elastic) and takes a permanent set when load is released. Material stretches but does not break. Ultimate strength is when it breaks and is higher than yield strength.
What is Characteristic yield strength of steel in terms of minimum yield stress and percent proof stress?
what is characteristic yield strength
What is the Significance of recrystallization temperature in metalworking?
Recrystallization temperature in metal working can be defined as the temperature at which the plastic deformation takes place perfectly. The stresses induced during the process is are grater than the yield strength and less than the fracture strength.
What is yield strength and tensile strength of 20c8 cast steel?
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
Is yield strength and proof stress same?
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
When a tensile strength test specimen begins to deform permanently it has reached its?
Tensile yield point or yield strength
What is the yield strength of plain concrete?
The yield strength in this case is equal to the ultimate tensile strength, which is about 0.9-3 MPa without any reinforcement.
What is the function of transition piece in pipe fittings?
Transition piece is mostly used where there is variation of Wall thickness greater tha 3/16" or the yield strength difference is greater than 20 ksi.
