Tensile Stresses in the main plates might result in tearing of main plate or cover plate across a row of the bolt.
The resistance offered by the plate against tearing is known as tearing strength or tearing value of plate.
Tearing efficiency of joints is given by,
\(\begin{array}{*{20}{c}} {{\eta _t} = \frac{\rm{Tearing\;strength}}{{\rm Strength\;of\;solid\;plate}}}\\ {{\eta _t} = \frac{{\left( {p - d} \right) \times t \times {\sigma _t}}}{{{p} \times t\times {\sigma _t}}} = \frac{{p - d}}{p}} \end{array}\)
\(\therefore \eta = \frac{{p - d}}{p}\)
Calculation:
Given that tearing efficiency = 0.60
\(\eta = \frac{{p - d}}{p}\)
\(1 - \frac{d}{p} = 0.6 \Rightarrow \frac{d}{p} = 0.4\)
