Material Strength Calculator

Tensile Strength Calculator

Calculate the tensile strength of a material based on maximum load and original cross-sectional area.

Maximum Load (N)

Original Cross-sectional Area (mm²)

Result

-- MPa

Formula

Tensile Strength = Maximum Load / Original Cross-sectional Area

Explanation

Tensile strength is the maximum stress that a material can withstand while being stretched or pulled before necking, which is when the specimen's cross-section starts to significantly contract. It is an intensive property, meaning its value does not depend on the size of the test specimen.

Yield Strength Calculator

Calculate the yield strength of a material based on yield point load and original cross-sectional area.

Yield Point Load (N)

Original Cross-sectional Area (mm²)

Result

-- MPa

Formula

Yield Strength = Yield Point Load / Original Cross-sectional Area

Explanation

Yield strength is the stress at which a material begins to deform plastically. Prior to the yield point, the material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be permanent and non-reversible.

Shear Strength Calculator

Calculate the shear strength of a material based on maximum shear load and cross-sectional area.

Maximum Shear Load (N)

Cross-sectional Area (mm²)

Result

-- MPa

Formula

Shear Strength = Maximum Shear Load / Cross-sectional Area

Explanation

Shear strength is the strength of a material or component against the type of yield or structural failure when the material or component fails in shear. A shear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force.

Young's Modulus Calculator

Calculate Young's Modulus (Elastic Modulus) based on stress and strain.

Stress (MPa)

Strain (mm/mm)

Result

-- GPa

Formula

Young's Modulus = Stress / Strain

Explanation

Young's modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. It is the ratio of tensile stress to tensile strain, where stress is force per unit area and strain is the proportional deformation.

Common Conversions

Approx. HRC = (HB - 104) / 6.2
Approx. HB = (HRC × 6.2) + 104
HV ≈ 1.04 × HB (for HB ≤ 400)

Explanation

Hardness conversion between different scales is approximate because each hardness test measures a different combination of material properties. The Brinell test uses a 10 mm steel ball, Rockwell measures depth of penetration under specific loads, and Vickers uses a diamond pyramid indenter. Conversion tables are based on empirical data.
