this method works only with prepreg, and preferable with higher resin content. Not to say that it need a very high resin content, just so it's not too dry. It's possible to do a test run of the process and see compared results using a plate where 1 piece is made this way, and the other is made...

I have 2 systems running ansys, one with quadrofx 3450 and the other with geforce 6800GT, and both are excellent, with a huge price difference. If you can afford pro opengl cards, go for the quadro line, otherwise, try and get the 6800GT or ULTRA. those are modifiable to quadro using riva tuner.

good idea... it does create a new entity, but probbaly better than offset.

I have the spacemouse, and it was the best spent $500 in my pro. career. in ansys you can manipulate the objects even in selection mode and you don't need to switch selection/action (f9), not to mention working with both hands on the model. only app where it has problems in ansys CFX - no support.

with parts which require very good surface qualiy, we use a very thin glass ply on the exterior. In any case, the first ply is applied, and that vacuumed onto the mold. after that, every several plies we do the same bagging. no need to do it in temperature. You can also use a glass ply on the...

Hi I need to convert a sketch into a 3d curve, for doing a bead in sheet metal. This is required for beads which are in mre than 1 plane. is there a simpel way to do it? right now I'm offsetting the sketch to get the 3d curve.

as long as the analysis is static, and can be simplified, there is no real need for FEM. In the real world, eventually you can into normal modes, frequency response and transient analysis. Those things are done only by computer FEM analysis, since any hand calculation is on a VERY basic level.

I assume you will be using PCOMP entries for modeling the composite. The problem with honeycomb material properties is that using a linear elastic material for the honeycomb is problematic. you will need to use "virtual" attributes, since honeycomb doesn't act like the regular poission ratio...

can you share the problems? sol600 is nice, it's almost like having msc marc, but with easier workflow.

I've begun my career in composites, mostly tooling design. this has been before and while studying. You should spend time on the floor, learning how those things are made, while using your acadmic background for better understanding. Since I'm more into structural design and analysis, I moved...

A revised note: got the dell 390 workstation today at work... it's certified and a real killer :)

Ok... I have the following at home: P4 3.4GHz, 2 GB RAM, and a GEFORCE 6800GT. no need for quadro, and I've worked on assmblies with thousends of parts. the importent things are: mid-high level CPU, at least 1 GB RAM, preferably 2, and a GOOD opengl graphics card. quadro is not...

Thanks. I have access to MATLAB. How do I need to scan those pics? I have the PDF version so I can just extract the graph. thanks again Jake.

I've joined a nice aviation company as their sole structural analyst, and had very little hand-calc experience prior to that. The hand calculations are not that difficult. If you know the basic rules, the stress/stran relations, and how to use the propere literature (bruhn, niu, etc.) you can...

Thanks :) I got my hands on the mil-std-810. I have a few other spectrums, which are shown in a graph, not in a table like the truck spectrum. How can I convert the graph to a table? TIA Jake.
