Hi;
I want to know how can i find the initial shape of a deformed structure.
I have a filament wound pressure vessel and i know that the optimum shape(after deformation) for the dome is a geodesic dome so i want to know the undeformed shape which produces that geodesic shape after loading with...
I am analysing a 3d composite(carbon/epoxy) pressure vessel with ansys using shell99 elements and i want to obtain tsai-wu failure criterian.I have only these properties:(1,2 or x,y are in plane 3 or z is out of plane)
MODULUS: E1,E2,G12
STRENGHT: Xt,Xc,Yt,Yc,S
POISON RATIO:NU12
but there are...

In filament wound structures such as pressure vessels what is the accuracy of layers thickness and fiber angles.for example can we say alayer is 1.1 mm thick and the fiber angle is 9.1 degrree or can we be more accurate like 1.11 and 9.12.

For an ansys analysis i need to know z direction(out of plane)material properties of on filament wound carbon/epoxy composite.but in handbooks i saw only the properties in x,y&xy directions.how can i have these properties.any help would be appreciated.

Hi;
I am analysing a 3D composite pressure vessel with ansys.I use shell 99 elements and want to know max. tsai-wu failure criterian.for material properties i have seen composite handbooks and there is only properties in directon 1,2 and 1-2 but there is not anything mentioned for direction 3.It...
I want to know how can i use ansys as a simulation tool for an external optimizer like matlab,a C program or anything else.can i use external optimizer inside ansys via user-defined optimization method.any help would be appreciated.

I want to know how can i call one FEM(like ansys)software from Matlab(optimization toolbar) and how can i make inputs and outputs beetween these two(making a loop until reaching the optimum result)

Hi;
I am working on optimizaton of composite pressure vessels and currently on the stacking sequence optimization.I have two design variables(fiber angle & layer thickness)and I want to optimize the weight.I prefer to use genetic algorithm for optimization and ansys for simulation.I am seeking a...

Hi;
I am working on layer optimization of composite pressure vessels with isotensoid filament winding.I am changing fiber angles and in each angle I optimize the thickness.since i want an isotensoid state it is necessary in each angle to change the opening of pressure vessel.so the dome geometry...
Hi;
I want to know what is the range of permeability of HDPE liners in CNG4 vessels in different pressures.is there any plots showing this.any help would be appreciated.
thanks
Hi;
I Want to know what is the range of filament winding machines accuracy in fiber angles and layer thichness,for example +-0.01 deg ,+-0.01 mm or more.
Thank You Very Much

hi,
I want to know how can i use genetic algorithm in ansys.i am working on layer optimization of composites and i want to join ansys package with a genetic algorithm program.
thanks
