[MW:7010] RE: 6995] Qualitative and Quantitative Testing

Sandesh,

 

            Impact tests measure the energy absorbed in fracturing a metal sample at high velocity and are used to quantify toughness. The crack tip opening displacement test is a fracture mechanics test which can be used to calculate the stress intensity at a sharp crack tip in the tested material as well as critical flaw sizes which will result in unstable fracture. Both tests provide quantitative results, however, the CTOD test requires additional calculations to achieve the desired output (normally a critical stress intensity).

Dear All

 

Kindly give us information about Qualitative and Quantitative Testing.
What is the difference between CTOD Test and Impact Test,Which one is Qualitative or Quantitative Testing.
 

Reply as soon as possible.
