Use of Tensile Testing for Automobile Enhancement

In automobile industries, the most important factor is the performance of the automobiles. The manufacturers in the automobile sector are always looking into ways to enhance the performance of the vehicles. Even the customers are always looking or better performing vehicles for them. This demands the buyers to ensure that they take all the steps to ensure the best performance of the vehicles they produce.

It is a global trend, as there are increasing efforts to minimise the weight of automobiles, increasing fuel efficiency that helps in the reduction of emissions. Many grades of steel are predominant material used to manufacture automobiles chassis and body. A new generation of sophisticated high-strength steels is created and produced to maintain the automotive industry’s demand for steel. Tensile Strength Tester is used to detect stress at which a material breaks or deforms.

Tensile testing is the simplest and popular mechanical tests. By measuring the force needed to elongate a sample to its breaking point, material properties are determined that allows designers and quality managers to predict material’s behaviour in their intended usage.

Many performance parameters are measured using tensile testing. The curve of force vs extension shows the tensile profile of the test up to the breaking point. The elastic limit and force to break is an important point to study the tensile profile. Various kinds of tensile testing include tear resistance, adhesion and bond strength, crimp joint pull-off force, peel, etc.

Advantages of tensile testing:

• Tensile testing of a metal helps the manufacturers in assessment of the amount of maximum tensile force that the metal can bear before it fails.
• Tensile testing gives information on the integrity and safety of materials, components and products.
• Helps manufacturers to ensure that the finished products are fit for purpose and are manufactured to its highest quality

Information gathered from tensile testing can be used in several ways:

• Reduction in material costs
• To analyse the batch quality
• To aid the design process
• Retain consistency in manufacture
• Complying with international and industry standards

Tensile testing assures the quality of components, materials and finished products in a broad spectrum of industries. Its applications include the automotive industry, construction industry, electrical and electronics industry, beverage industry, aerospace, paper and board industry etc.

Application of tensile testing in:

• Paper and board industry are folding characteristics of boxes and cartons, the open ability of card and paper based packaging, force to separate multi-part documents etc.
• Tensile Strength Testing of packaging materials used in packaging Industry is force associated with opening pop-caps, snap-caps and various push pull closures, elongation of plastic packaging materials, adhesive or peel testing of adhesive bonds, labels and container seals.
