## Calculation

### Length of bolts in threaded holes

$\text{if }\ \text{type }$$\text{of }$$\text{material}= \text{Austenitic steels}$
$$l_b=\max\left(0.8\cdot d_n\cdot\max\left(\cfrac{R_{p0.2/bolt/T}}{R_{p1.0/T}}, \cfrac{R_{p0.2/bolt/T_{test}}}{R_{p1.0/T_{test}}}, \cfrac{R_{p0.2/bolt/T_{assembly}}}{R_{p1.0/T_{assembly}}}\right), 0.8\cdot d_n\right)$$
$\text{else}$
$$l_b=\max\left(0.8\cdot d_n\cdot\max\left(\cfrac{R_{p0.2/bolt/T}}{R_{p0.2/T}}, \cfrac{R_{p0.2/bolt/T_{test}}}{R_{p0.2/T_{test}}}, \cfrac{R_{p0.2/bolt/T_{assembly}}}{R_{p0.2/T_{assembly}}}\right), 0.8\cdot d_n\right)$$
