tensile strength

Thân thiện

A steel cable demonstrates high tensile strength by supporting a heavy weight.

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.
