Engineering Stress And Strain

Calculate material stress and strain.

Engineering stress is the ratio of load over the unstressed cross section area. Engineering strain is the ratio of change in length over the unstressed length. The elastic modulus is the ratio of engineering stress over engineering strain. Engineering stress and strain ignores the change in cross section area and length as a load is applied.

CALCULATOR : Typical Density Elastic Modulus Poisson Ratio Bulk Modulus Shear Modulus And Thermal Expansion Coeficient [FREE] ±

Calculate typical elastic modulus, shear modulus, bulk modulus, density, and thermal expansion coefficient of a solid.

The table values of Poisson ratio and bulk modulus are calculated from the elastic modulus and shear modulus. Use the Result Table option to display a table of properties versus material type.

Tool Input

ρ : Density
E : Elastic Modulus
G : Shear Modulus
K : Bulk Modulus

CALCULATOR : Pipeline Axial Stress From Temperature And Pressure [PLUS] ±

Calculate pipeline axial load and axial stress from operating temperature and pressure.

The axial stress is caused by changes in temperature and pressure between installation and operation. The external pressure is assumed to be constant during installation and operation (submerged pipeline). The internal pressure is assumed to be zero during installation. The stress is positive in tension, and negative in compression.

Nominal pipe diameter and wall thickness should normally be used for axial load calculations. Pipe wall stress is calculated for the cross section area, and is indicative only.

CALCULATOR : Pipeline Equivalent Stress [PLUS] ±

Calculate pipeline operating axial load, combined stress, hoop stress, longitudinal stress, bending stress and torsion stress.

Stress is positive in tension, and negative in compression. The external pressure is assumed constant for installation and operation (submerged pipeline). The internal pressure is assumed zero for installation. The axial stress is caused by changes in temperature and pressure between installation and operation. The combined stress can be calculated using either Tresca's or Von Mises' formula.
