How do you read a stress strain curve?

The stress-strain relationship is displayed on an x-y graph, where the y axis (vertical axis) represents stress, and the x axis (horizontal axis) represents strain (as seen in Figure 2). Therefore the stress-strain slope (change in y over change in x) is Stress divided by Strain.

What does a stress strain curve tell us?

A stress-strain curve is a graphical way to show the reaction of a material when a load is applied. It shows a comparison between stress and strain. Stress is the ratio of the load or force to the cross-sectional area of the material to which the load is applied.

What are the properties of textile Fibre?

The essential or primary properties of a textile fiber include:

• High Length to Width Ratio: For any fiber to be spun made to yarn and then into fabrics is that their lengths must be more than their widths.
• Tenacity:
• Flexibility:
• Spinning Quality or Cohesiveness:
• Uniformity:

How do you identify textile fiber?

Fibres can be identified from very small yarn samples. Typically, 0.4 cm (1/8″) or less is clipped from an exposed yarn end in good condition in an inconspicuous area. Both warp and weft yarns should be sampled because some fabrics are made of one fibre type in the warp and another in the weft.

How do you read yield stress on a graph?

1- Find point 0.2\% on the horizontal axis of the graph (strain axis). 2- Draw a line parallel to the elastic region of the graph. 3- The 0.2\% yield stress is the point where your drawn line met the stress-strain curve.

What is elastomers explain with stress strain curve?

An elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young’s modulus and high failure strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber.

What is the property of textile?

Textiles are specific types of materials characterised by a unique combination of properties including strength, flexibility, elasticity, softness, durability, heat insulation, low weight, water absorbency/repellence, dyeability and resistance to chemicals.

What are four properties of textiles?

When looking at basic properties of fabric, there are certain features which are necessary to consider; breathability, weight, drape, durability, softness, construction and whether it is a water-repellent fabric.

How do you identify a textile fiber through chemical test?

Burning Test: In this test, a bundle of fiber is ignited at one end and the smell, color, shape of ash or bead is noted. Further, other characteristics such as burning slowly or rapidly, melting or not melting etc., are also observed.

How do you identify textiles?

Short of taking your fabric to a lab for identification, the fabric burn test is the most dependable way to determine a fabric material of unknown origin. A fabric burn test won’t tell you the exact name of the fabric you’re dealing with, but it will help you match laundering and pressing needs.
