I have a reactangular cavity that needs to be filled with glass polypropylene mixin an injection molding process. IS there any formula which will tell me how mucg pressure is required for the cavity to be filled with the mix?
Before you use an FEA software, you may want to do some hand calculation. One of the better books which may help you is by Jack Vinson from Univ of Delaware.
Otherwise as SWC has mentioned you do the modelling like aany other problem but need to be careful while defining the orthotropic...
I have done extensive structural calculation for composites but recently ran into a thermal one. The composite is a Carbon Prolypropylene mix with fiber volm of 50%. How do I calculate the conductivity and Specific heat of the compsite? Is it OK if I take the average of Carbon and PolyP?

I found IDEAS-TMG and IDEAS-ESC to be much better than PRO-E thermal package. Its not that you will go and buy these packages as they cost a lot. TMS is for mostly radiation dependant problem and ESC for flow dependant problem. And its all tied to the IDEAS solid modeler.
Its almost 6 years since I have dealt with transient HT. So bear with me if the question is frivolous.
I have a 1-D sample with both sides being held at say 150C.
I want to find out the time taken for the mid plane to reach a temp (say 100 C)
How do I solve the follwoing transient 1-D HT...

I have been using a heat transfer co-efficient h = 5 W/m^2 K for free convections from a flat surface. Does anyone have a graph or literature which gives the h values of air relative to air velocity and temperature for a flat surface?
Thanks in advance
