Thanks Fearn interesting,,,A fascinating read.
As the auther says though....
"I did not use real values for the geometry. I used generic structural steel material properties and did not account for the variation in modulus from the differential heat treatment or hardening. I did not check for mesh convergence, or verify my results were in accordance with the beam equations. I did not apply realistic loading conditions. In other words, please take these results with a grain of salt!"
As many of those factors are critical in the design & forging of kukris I think his advice to take with a grain of salt is correct.
But Many good points raised especialy re. reduction in transmited shock & vibration I think. I hadnt considered that before. I am sure thats a valuable hypothisis.
