Hi All, Any help would be hugely appreciated. I have a question about both the bending moments and deflection equations for stiffeners in...
Perfect, thanks for your help
I am still unsure of what the correct procedure is. Once the fiber weight of the panel has been found, this fiber weight is then used in the...
Thanks for the reply. So say if it was chop strand matt and in ISO C for a complex panel you must use a fiber weight of .25 and the derived...
Hi there, Wondering about ISO B properties. So if you do the small amount of testing required to validate the fiber weigh fractions used, must...
Sorry, must have been looking at an older version...I have looked at the most recent and this correlates so this must have been a mistake.
Hi there, I have been puzzling for ages where the values of Qi comes from in Table H.4 in ISO 12215-5. the value is 7.07x10^8 which is in the...
Does anyyone know where the loadpoint should be taken for a WT bulkhead. Is it a third of the way up the bulkhead or half way....A little confused
Thanks Ad Hoc
Does anyone know if you are able to use the CSM tie layer in the minimum skin weight requirement for DDNV high speed craft?
Hi, Thanks for this. Yes you are right. I also presume this stays within reasonable limits for small deflection theory too...
Does anyone know how this number is derived? Its in the ISO rules for calculation the required minimum outside skin inertia. I just can figure out...
Well on bending moment, it is a squared function in the ISO rules. 1 squared is 1 and 0.5 squared is 0.25. 1/.25 = 4 . So yes, 4 times the bending...
Sure yes I understand. The equation wouldn't make sense otherwise. I just think this is not realistic as you only have to change the size of the...
I was just wondering about the curvature correction factor Kc. Can you use it for all panels regardless of the short span direction or can you...
Ah that's the one. Thanks so much
Does anyone have a link to the paper written by a lady SP Gurit employee about best stringer / hull plating combination for weight saving? I saw...
Yes, I'm a divorced insomniac living in a shed with wifi.
I was wondering. If you had a stack of differing plies, e.g. Glass uni directional, CSM, double bias, quadrax etc.and were going to test them in...
I think that sounds spot on. Is there anyone out there who agrees with this or knows this to be the case? It makes sense to me this way....
