OK thanks everyone for your replies. We are a relatively small company. The parts they want to laser cut are tertiary structure, equipment shelves, small brackets to support lightweight items in the cabin, that kind of thing. I am the structures CVE on the project so ultimately its up to me...
OK sorry if i wasnt clear enough! Im a stress engineer and my job is to ensure parts are strong enough and safe to fly. There are some components that i have done some analysis on, based on the assumption that the parts are mechanically cut, but the customer is now asking me if it is OK for...
Of course i have tried Googling the topic, i just cant find any quantatitive data and neither does the customer im working for. The Vans story is interesting, but doesnt answer my question. Thanks anyway!
Hi all,
Does anyone have any information on heat affected zones for laser cutting of aluminium? Ive not been able to get any data off the company doing the cutting, therefore im going to have to make some conservative assumptions on the HAZ for the stress analysis. Ive never worked with laser...
Hi, thanks for your replies. Ive been a stress engineer for 20 years and have used the equations for 'buckling of thin sheets' given in chapter 11 of 'Airframe Stress Analysis and Sizing' by Michael Niu many times for the analysis of panels, webs etc. but i was just wondering if there was a...
Apologies, i asked completely the wrong question! What i meant to ask was what classifies a panel as 'thin' - not 'flat'! Apologies again for the confusion!
Hi,
Im looking to do a thin panel buckling analysis - but what actually classifies a panel as being 'thin'? I remember hearing somewhere that it was to do with the relationship between the width and the thickness, but cant find anything written down. Can anyone help? Thanks.
We are looking to take on an Aerospace Mechanical Engineering apprentice and I would like to give the candidates a problem to solve during the interview. I dont want anything too technical, just something that will give us an insight into how they approach problem solving, we are looking for...
