Report requirements:

1 - Main purpose of laboratory work - to study different tension diagrams of plastic and fragile materials, to calculate main strength characteristics of investigated alloys;

2 - to draw diagrams of tension for low-carbon steel and cast-iron in coordinates F=function(delta_l) (force in kN; real elongation in mm) and sigma=function(epsilon) (normal stresses in MPa; relative deformation in %);

3 - to calculate yield strength, ultimate strength and failure stresses for low-carbon steel; to calculate proportionality limit stresses and failure stresses for cast-irons;

4 - to calculate residual relative plastic deformation de ... Читать дальше »
