What’s Breaking Strength?

Breaking strength, also known as tensile strength, is the point at which materials deform or break under a given load. Throttling occurs when a material is pushed to failure. Tensile testing is used to identify breaking strength, and ultimate tensile strength is measured by force per unit area. Brittle materials are most often tested for breaking strength. The test involves gradually applying force to a sample until it deforms irreparably or breaks.

Breaking strength is more commonly known as tensile strength. It is defined as the point at which certain materials deform or break under a given load. The point at which the material reaches breaking strength is described as a kink.

Throttling occurs when a material is pushed to failure or tensile strength. As the material is pushed to the brim, the cross section begins to contract significantly. In the engineering world, breaking strength is simply described as the opposite of compressive strength.

The breaking or tensile strength of a given material is identified by tensile testing. During the procedure, information about the stress of the material is recorded as different amounts of strain are applied. The readings are graphed and the point on the curve that is reached before the material begins to stretch indicates the breaking load or breaking load of the material. The numbers indicated by such tests indicate the maximum load that a material can withstand before it breaks or becomes irreparable.

Ultimate tensile strength is usually found by noting the force a material can withstand per unit area. The most common forms of measurement used to arrive at the tensile strength of materials are the pounds of force it can take per square inch or the kilo/pounds it can take per square inch. These measurements both equal 1,000 pounds or 453.59 kilograms per square inch. For convenience, the most commonly used measure is kilos/pounds per square inch, also known as KSI.

Measurements of breaking strength are most often calculated for brittle materials. Materials considered brittle include alloys, composites, ceramics, plastics, and wood. Tensile strength would be important for these materials because they are materials that are easily deformed or broken. While tensile strength can also be used in the case of those materials considered ductile materials, this is rarely the case as such materials tend to be less susceptible to cracking and it is less important to know the force that will damage them.

The test for calculating the breaking strength of any given piece of material is quite simplistic in nature. A sample of the material is taken and then placed in a machine which grabs the material. The machine then gradually applies force and begins a pulling motion; this traction movement continues until the material deforms to the point of making it irreparable or until the piece of material breaks. The point before cracking or irreparable deformity becomes the information recorded as the breaking strength of that specific type of material.
