apc 1Axial Force on fillet Weld formula

\(\large{ \sigma = \frac{ 1.414 \; P }{  h \; \left( l_1 \;+\; l_2  \right)   }     }\)  
\(\large{ l_1 = \frac{ 1.414 \; P \; c_1 }{  \sigma \; h \; w  }     }\)  
\(\large{ l_2 = \frac{ 1.414 \; P \; c_x }{  \sigma \; h \; w   }    }\)  

Where:

\(\large{ \sigma }\) (Greek symbol sigma) = stress in weld

\(\large{ w }\) = distance between weld

\(\large{ c_1 }\) = distance from shear centre of weld

\(\large{ c_x }\) = distance from shear centre of weld

\(\large{ l_1 }\) = length of weld

\(\large{ l_2 }\) = length of weld

\(\large{ P }\) = total axial force

\(\large{ h }\) = weld throat thickness
