Chapter 7, Problem 7.5P

Interpretation Introduction

Interpretation:

Whether the component will fracture at 0.5 mm surface crack or not needs to be explained.

Concept introduction:

Fracture toughness can be calculated using the following formula:

$k_{IC}=f\sigma \sqrt{\pi a}$

Here,

$\begin{array}{l}F=\text{ geometry factor of flaw and specimen}\hfill \\ \sigma =\text{stress applied}\hfill \\ a=\text{ flaw size }\left(\text{have crack length}\right)\hfill \\ k_{IC}=\text{fracture toughness}\hfill \end{array}$
