Any people know how to correlate toughness and impact stength together for a
material, and how to correlate modulus and hardness? Thank you! | F****y 发帖数: 145 | 2
There are discussions in detail about the correlations between
fracture-toughness and Charpy Energy in R. W. Hertzberg book (Deformation and
Fracture Mechanics of Engineering Materials, Ch.9). Table 9.3 lists some
correlations.
The hardness of a metal is about 3 times larger than its yield strength.
In general, the hardness of a engineering material is about 2 to 3 times
larger
than its yield strength.

however those coorelation curves are not always reliable, whenever
there are other methods, these corelation curves should be avoided
during precise calculation.
For rough evaluation, these curve will give a good approximation.
