Stress-Life Diagram (S-N Diagram) - UiS

Through many years of experience,empirical relations between fatigue and tensile properties have been developed.Although these relationships are very general,they remain useful for engineers in assessing preliminary fatigue performance.The ratio of the endurance limit S e to the ultimate strength S u of a material is called the fatigue Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextShort-Time Creep,Fatigue and Mechanical Properties of The proper selection of materials for the intended use of the structural member is of particular interest.The paper deals with determining both the mechanical properties at different temperatures and the behavior in tensile creep as well as fatigue testing of tensile stressed specimens made of low alloy 42CrMo4 steel delivered as annealed and cold drawn.
