What are the mechanical properties of low carbon steel and cast iron in torsion?
Low carbon steel high elongation, under compressive load, initial deformation is small, the size of the force along the straight line rise, further increase the load when the specimen is compressed into a drum and finally pressed into pie without damage, so the ultimate strength cannot be determined. That is to say, when the low carbon steel is compressed, the elastic modulus E and the yield limit S are the same as those in the tensile, and there is no compressive strength limit.
Cast iron is a brittle material with little tensile strength, no yield and necking, and strain before breakingVery small.
Low carbon steel is a kind of plastic material with great tensile strength. It is divided into elastic stage, yielding stage, strengthening stage and local changeShape stage.
