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.
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
Cast Iron because of its strength and mass
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
The breaking strength is always greater than the yield strength.
Yield strength is a form of tensile strength, as yield strength is maximum strength upto which a material retains its original shape or it is in elastisity above which it will in plasticity.
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
what is characteristic yield strength
Cast Iron because of its strength and mass
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
Tensile yield point or yield strength
The yield strength in this case is equal to the ultimate tensile strength, which is about 0.9-3 MPa without any reinforcement.
The percent yield in this case is 89,25 %.
Steel is iron mixed with carbon, the amount of carbon changes the specifications of the steel (strength, elasticity,...)
