Thanks all for your feedback. Den Hartog is defly a value for money. Between Thomson and Rao, what would be the primary differences? Are they both undergrad/grad level text books? Does one deal with more specialized apps than the other? Thanks...

Thanks GregLocock ! This really helps.

Can you provide me with title and author of a few good textbooks on Vibrations? Thanks...

All, Is calling out SPCC on my drawing same as CRS1018? They are both cold rolled steel right? So is CRS 1018 more specific compared to SPCC? Could some one help me to exactly differentiate between these material call outs? Thanks in advance....

Thanks ariansdad, You answered my question. I am looking for the thermal time constant which is time taken to reach 63% of the final asymptotic value (steady state temp) Thanks again all for your time in answering my q's.

ariansdad, I am looking for thermal time constant. I am not sure I understand your equation though. What is this length in the equation? I am new to HT sims and dont recall this term from my ht classes. thanks

Well, sorry I was not clear before. I am running a transient heat transfer on a part where conduction and convection are the primary modes of ht. If I extend the duration of my sim I can see that my time vs temp plot will approach asymptotic inf. So from one such plot how will I estimate the...

From a plot of temp vs time how can I calculate the time constant? Is that the time when the slope goes to 0 or the temp reaches steady state? Thanks,

Thanks Heckler, Unfortunately I couldnt find what I was looking for in 3M. TC-2707 is thermally conductive (electrically insulative). I need electrically conductive.

All, I am looking for complete thermal properties for electrically conductive epoxies. These properties are hard to come by (atleast from what i have seen online) and so I will take what I get and not worry too much about minor changes in components. Thanks in advance....

Ok. That was way too vague. Let us say CMOS image sensors. I can find data sheets from manufacturers which give an operation range of temperatures. That is not what I am looking for. I was wondering how much heat would get generated when these sensors operate. (could be whatever time the data...

Hi all, I am looking for some info on typical heat generated by image sensors. Can any one give me an idea or point me to an appropriate location on the www? Thanks,

Thanks GBor. I will try that and let you know.

GBor, As always thanks for your response. Unfortunately due to restrictions am unable to share the model. The solid model was built in Solidworks and all the features such as fillets, chamfers, drafts (ah ! yes it is Plastic)were removed. However this one part that comes up with the...

Hi All, I am having problems with a complicated solid model that I am trying to automesh. It is a big assembly and one of the parts gets flagged as it was not successfully surface meshed. However this part is able to solid mesh without any hassles. However a part that did not get flagged...
