<div dir="ltr">Hi !<div><br></div><div>I have been studying the psub spreadsheat and found a inconsistent formula compared to the ABS Rules for Building and Classing Underwater Vehicles.</div><div>It`s in cell <b>C48: Pm= Von Mises Shell Buckling Pressure for a Cylinder.</b><br>
</div><div><br></div><div><span style="font-size:11pt;line-height:115%;font-family:Calibri,sans-serif"></span><span style="font-size:11pt;line-height:115%;font-family:Calibri,sans-serif"> C48 </span><font face="Calibri, sans-serif"><span style="font-size:15px;line-height:17px">=2,42*C6*(C26/C17)^2,5/(1-C7^2)^0,75<font style="background-color:rgb(255,0,0)" color="#000000">/</font>(C14/C17-0,45*(C26/C17)^0,5)</span></font></div>
<div><font face="Calibri, sans-serif"><span style="font-size:15px;line-height:17px"> ^</span></font></div><div>The division sign I have highlighted above in the spreadsheet formula should.. (if you look at the ABS formula section 6 - 19.5.1 Inter-Stiffener Strenght).. be a Multiplicator.</div>
<div><div><br></div><div>But changing this gives me a low Maximum psig for inter-stiffeners.</div><div><br></div><div><br></div><div>I`m confused! Could someone please explain this? :-)</div><div><br></div><div><br></div>
