Metals and Alloys - Young's Modulus of ElasticityĮlastic properties and Young's modulus for metals and alloys like cast iron, carbon steel and more. The influence of temperature on the strength of metals. Some typical properties of engineering materials like steel, plastics, ceramics and composites. Loads - forces and torque, beams and columns.īarlow's Formula - Calculate Internal, Allowable and Bursting PressureĬalculate pipes internal, allowable and bursting pressure.Ĭompression and Tension Strength of some common MaterialsĬommon materials and average ultimate compression and tension strength. In general both stress and temperature influence on the rate of creep.Normally creep strength decreases with temperature.Īllowable creep strain can be specified - typical 0.1 %/year for steel bolts and pipingįorces, acceleration, displacement, vectors, motion, momentum, energy of objects and more. The time dependent deformation due to heavy load over time is known as creep. Fatigue limit, endurance limit, and fatigue strength are used to describe the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure.Steels - Endurance Limits and Fatigue Stress Steel Tensile Strength - (Ultimate Tensile Strength) - of a material is the limit stress at which the material actually breaks, with sudden release of the stored elastic energy.Most steels have an endurance or fatigue limit about half the Tensile Strength. Yield strength is defined in engineering as the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation. Fractures occur at stress less than the material Yield Stress. Creep - when a material is subjected to a load for a very long time it may continue to deform until a sudden fracture occursįractures due to fatigue is common in cyclic loaded parts like connected rods, crankshafts, turbine blades, railroad wheels and so on.Fatigue - when a material is subjected to repeated cycles of stress or strain and its structure breaks down and ultimately leads to fracture.
