Ultimate Tensile Strength vs Maximum Load (F)

Vedi formula →

Formula

## Ultimate Tensile Strength The ultimate tensile strength (UTS) is the maximum engineering stress a material can sustain before fracture in a standard tension test. ### Formula **UTS = F_max / A_0** where F_max is the peak load recorded during the tensile test and A_0 is the original cross-sectional area of the specimen. This is an engineering stress (based on original area), not true stress.

Esempio Risolto

A 10 mm diameter steel rod fails at 45 kN.

  1. 01Area of 10 mm diameter rod = pi × 5² = 78.54 mm²
  2. 02UTS = 45000 / 78.54 = 572.9 MPa
