Hyperform ALTAIR --> Shell 3D to 2D

Rahul_P1

Hi,

I have optimized a 3D shell part.
I have my correct stacking with all my plies.
Now, I would like to manufacture my part by stamping process (thermoplastic thermoforming)

do you know whether is there a tool in hyperworks which flatten the part to 2D shell ? taking account of the displacment of plies (shearing, tension, bending...) ?
I can foresee the right size of my plies and avoid the wasting of material.

Do you know if Hyper form can do this ?

Many thanks

Benoit

Benoit,

HyperForm 1Step analysis will take the 3D part shape as input and gives stress, strain, thickness distribution plus the 2D blank required to form the 3D part. This can be done using steel and aluminum considering the thermal effects but I am afraid this is not available for a composite material however steel could be a rough approximation for you to continue your project.

Radioss block can simulate a full scale incremental forming simulation for composite materials which includes moving tools with all the process parameters and thermal effects. Here you will be able to see the shear and bending of plies in detail. However incremental analysis, unlike 1Step, starts with a 2D blank shape and gives out the 3D part shape.

Perhaps you can setup a composite forming model using HM-Radioss

The support for composite materials is most likely in 13.0

Please check back with us during the next update/version and we will let you know, every new addition/change to the tool will be mentioned in the release notes of the update/version.
