For zircon for the same flaw size, the intensity factor is more than alumina.
View Answer Explanation
The largest constituent elements and flaws increase the flexural strength.
Which of the following shows the best fracture strength?
What is tensile strain?
Find the strain of a brass rod of length 250mm which is subjected to a tensile load of 50kN when the extension of rod is equal to 0.3mm?
Find the elongation of an steel rod of 100mm length when it is subjected to a tensile strain of 0.005?
A tensile test was conducted on a mild steel bar. The diameter and the gauge length of bat was 3cm and 20cm respectively. The extension was 0.21mm. What is the value to strain?
i) Strain is a fundamental behaviour of a material. ii) Strain does not have a unit.
