Definition

Noun: - The maximum amount of tensile (pulling) stress a material can withstand before breaking or failing. It is a fundamental property of materials, expressed as force per unit area (e.g., pounds per square inch or megapascals). It measures a material's resistance to being pulled apart.

Usage

• Tensile strength is a critical specification in engineering, manufacturing, and construction to ensure materials are fit for purpose.
• It is determined through standardized tests where a sample is pulled until it fractures.
• The term is used when comparing materials, designing components, and setting safety standards.

Examples

Advanced Usage

• "Ultimate Tensile Strength (UTS)": The maximum stress a material can withstand during a tensile test, recorded at the point of fracture.
  • The datasheet lists the alloy's ultimate tensile strength as 450 MPa.
• "Yield Strength": Often discussed alongside tensile strength, this is the stress at which a material begins to deform plastically (permanently) and will not return to its original shape.
  • The component was designed so the operating stress remains below the yield strength, even though the tensile strength is higher.

Variants and Related Words

• Tensile (adjective): Related to or involving tension; capable of being stretched.
  • Tensile forces act to elongate the beam.
• Strength (noun): The quality or state of being strong. In materials science, it often requires a modifier (e.g., , , ) to specify the type of load.
  • The overall strength of the structure depends on several factors.

Synonyms

• Breaking strength
• Tensile stress at break

Related Concepts (Not Phrasal Verbs or Idioms)

• Ductility: A material's ability to deform under tensile stress (e.g., stretch into a wire) before breaking. A material can have high tensile strength and low ductility (brittle) or high ductility (ductile).
• Stress-Strain Curve: A graph that plots a material's stress against its strain, from which properties like tensile strength, yield strength, and modulus of elasticity are derived.

Noun

1. the strength of material expressed as the greatest longitudinal stress it can bear without tearing apart
