Tensile Test, Part One

Tensile Test:
    Tensile test is a simple test, wherein the specimen in question is subjected to uni-axial load (pulled apart) till failure. This test is used to plot the stress - strain curve there by coming to conclusion about
  • Yield point
  • Elasticity limit
  • Point of  Proportionality
  • and lot more factors including, true breaking stress, fracture point load, ...

 
   A sample of specimen is taken, and is pulled apart in apparatus known as Universal testing machine. The length and cross section area of sample are decided as per our needs. Nomenclature of the specimen is shown in figure.


    Once the equipment is set up, the load on the specimen is gradually increased noting down the stress and strain levels till the point of rupture (i.e. fracture). A typical curve for ductile materials is shown here:

In figure,
the points to be noted include: 
  • Proportionality zone .. i.e the zone where HOOK's law is valid
  • The region where elasticity is exhibited
  • The zone where material yields and plastic deformation happens
  • The ultimate tensile strength & the uniform elongation of specimen till then
  • The fracture point and the local necking which happens before fracture

  12. Thank you for sharing information on the determination of tensile strength of cotton grey fabric by the strip method. Understanding this process is crucial for ensuring the quality and durability of textile materials. By using a reliable tensile strength tester, manufacturers can accurately measure the force required to break the fabric, which helps in assessing its overall strength and performance. This method not only aids in quality control but also informs decisions in fabric development and production processes.
