Tensile Strength Calculator | Free Online Tool for Material Testing

Introduction

Tensile strength is one of the most critical mechanical properties in materials science and engineering. Whether you're working with metals, polymers, textiles, or composites, understanding tensile strength helps ensure your materials meet quality standards. Our free online Tensile Strength Calculator simplifies this essential calculation - allowing engineers, students, and quality control professionals to quickly determine material strength properties.

What is Tensile Strength?

Tensile strength measures a material's resistance to breaking under tension. It's defined as:

Tensile Strength (σ) = Force (F) / Cross-Sectional Area (A)

Expressed in Pascals (Pa) or pounds per square inch (psi), this value indicates how much stress a material can withstand before failure. There are three key tensile strength measurements:

1. Yield Strength - When permanent deformation begins
2. Ultimate Strength - Maximum stress before breaking
3. Breaking Strength - Stress at fracture point

How to Use Our Tensile Strength Calculator

Our calculator provides instant results with support for multiple units:

Step 1: Enter Force Value

Step 2: Enter Cross-Sectional Area

• Input the area perpendicular to the force
• Choose from m², mm², or cm²

Step 3: Select Output Unit

• Get results in Pa, MPa, or psi

Step 4: View Results

• The calculator displays tensile strength in your preferred unit
• Error checking ensures valid inputs
