tensile strength

Examples of tensile strength in the following topics:

• Reinforced Concrete Construction

  • Reinforced concrete is a composite material in which the low tensile strength of concrete is reinforced with a material such as steel.
  • Reinforced concrete is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement with a higher tensile strength and ductility.
  • Tensile strength is defined as a stress, measured as force per unit area, that a material can withstand before failing.
  • Having a low tensile strength, in combination with low ductility (i.e. the ability to bend), means a material is more likely to break without reinforcement.
  • If a material with high strength in tension, such as steel, is placed within the concrete, the composite material (reinforced concrete) resists not only compression, but also bending and other direct tensile actions.

• Alloys

  • Physical properties (density, reactivity, conductivity) of an alloy may not differ greatly from those of its constituent elements, but its engineering properties (tensile strength and shear strength) may be substantially different.

• Abnormal Contractions of Skeletal Muscle

  • A spasm may lead to muscle strains or tears of tendons and ligaments, if the force of the spasm exceeds the tensile strength of the underlying connective tissues, such as with a particularly forceful spasm, or in the case of weakened connective tissues.

• Clinical Advances in Bone Repair

  • For orthopedic uses, metals such as tantalum or titanium are often used because these metals exhibit high tensile strength and corrosion resistance, along with excellent biocompatibility.

• Stress and Strain

  • A material with a high elastic modulus is said to have high tensile strength.

• Characteristics of Connective Tissue

  • Collagen fibers are fibrous proteins and are secreted into the extracellular space and they provide high tensile strength to the matrix.

• Types of Connective Tissue

  • With the tensile strength of collagen, this tissue forms tendons, aponeurosis and ligaments.
  • It has relatively high compressive strength, but poor tensile strength, and very low shear stress strength.

• Characteristics of Condensation Polymers

  • The presence of polar functional groups on the chains often enhances chain-chain attractions, particularly if these involve hydrogen bonding, and thereby crystallinity and tensile strength.
  • Cold-drawing is an important physical treatment that improves the strength and appearance of these polymer fibers.

• Fracture

  • Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture.
  • This is usually determined for a given specimen by a tensile test, which charts the stress-strain curve .
  • The final recorded point is the fracture strength.

• Arches and Domes

  • Arches and domes are structures that exhibit structural strength and can span large areas with no intermediate supports.
  • Arches and domes are structures that exhibit structural strength and can span large areas with no intermediate supports.
  • They span large areas by resolving forces into compressive stresses and eliminating tensile stresses (referred to as arch action).
  • Domes have the same properties and capabilities of arches, they can span large areas without intermediate supports and have a great deal of structural strength.
  • Explain how an arch exhibits structural strength and how a dome can span a large area without intermediate supports
