ADVANTAGES AND DISADVANTAGES BETWEEN THE HOLE DRILLING AND RING CORE METHOD
The Hole drilling method is a well known calculation method with a wide range of strain gages and accessories. It is also compliant to the ASTM E837 Standard. A couple of disadvantages are a lower depth of investigation and greater sensitivity to the error of eccentricity.
On the contrary, the best advantages of the Ring Core Method are:
- Higher depth of investigation
- Higher sensitivity to the strains
- Lower sensitivity to the eccentricity error
