Risk assessment in Finite element Modelling

Risk assessment in Finite element Modelling

(OP)
Hi i am civil engineer researcher

it is required from me to do risk assessment for my project (FE)

for example
1.lost of data is one of risks

but i can think of else other than this, espically that my project is on computer.

Please help

RE: Risk assessment in Finite element Modelling

Please clarify what you mean by risk assessment for your project. Do you want a risk assessment on doing FEA? Do you want a failure modes analysis for your structure? Do you want operator errors for doing analysis/FEA? Do you want to know the limits of FEA?

RE: Risk assessment in Finite element Modelling

Many FEA reports I have seen always come with the qualification that the modelling should be verified against physical test data! I have always considered this as backside covering by a consultant not wishing to be sued. It also reflects the risks associated with modelling technique, boundary definition and any other assumptions made by the modeller. One common risk is assuming physical data is linear because the the modeller doesnt have non linear information or the software to emulate the behaviour of such materials.

Suggest you read up on the limitations of FEA. Its a grea t tool but if the boundary conditions are not correctly modelled you get erroneous results.

I thought computers and computer software like FEA made us even perfecter engineers; able to do even dumber things, with even less real understanding, more complexly, in the way of structures and details and still COA. And, now you suggest there are risks involved, boy that ruins my day. I just hired three people fresh off the street, gave them pretty new desks and computers, with some super-duper softwares, and called them all engineers, and now you tell me. All three of them have already come to me and said I missed installing some really important softwares, like twitter, facebook, something about shopping netswork, and two of them wanted to know about Eng-Tips in case they had some really important engineering questions, like how high is up, or what about simple beams, do they really bend. One of them Googled it, but still couldn’t figure out what percentage of the elastic modulus the section modulus was, obviously it couldn’t be 100% or it wouldn’t be just a section. What Risk?

Hey all,
I most likely concerned with risks on health ,time ,effort, and money

And your answers was useful as well.

Thank you

RE: Risk assessment in Finite element Modelling

If your project is funded, then you have to look at all the potential issues that could affect their investment. Hardware failure, data loss, you becoming sick or worse, those are all loss events. There is also the potential that someone else is researching the same thing as you in parallel and that the IP is compromised. Things could prevent publication and diminish the value of the research. Issues with peer review, etc.

"...One of them Googled it, but still couldn’t figure out what percentage of the elastic modulus the section modulus was, obviously it couldn’t be 100% or it wouldn’t be just a section."

This is very wise, very zen. This reminds me of the time when a person described the principle of superposition as "similar to normal position, just typically better."
