Maximizing Shear Strain

You then need to assign a certain region as design space and certain other regions as non design space,

to define a Non-Design Space for optimization, you need to create a separate component and property. It is necessary to either separate the areas on a geometry level (i.e. before meshing) or on the element level (after meshing).

After meshing, you still can move areas to the Non-Design component. Please use the 'organize' function within HyperMesh.

The following movie shows all necessary steps on a simple part:

Hi;

Thank you very much for your answer but my intention was to ask to setup a topology optimization for one region of my design.I already organized my components and mesh region.

I want to maximize Shear Strain of Design Space..but how any idea?

Hi,

Maybe you can use exclude elements option when creating response for strain? Try this.

Hi Prakash ;

Firstly thank you for your answer..But i want to increase  'shear strain' in my non-desing domain.such that

I created my model design domain/component and non-desing Component.I want to increase or maximize the shear strain energies (objective)  of non-design elements targeting  the topology of design space.

I hope i am clear..I want to find best topology of my design space that maximize/increase the shear strain of non-design elements.

Or i want to know if there is any option maximize shear strain/shear strain energy/ESE of any component.

Regards

Hi,

First of all, using strain as a response is not at all recommended for a topology optimization. 

You can request shear strain through Control cards>> Strain>> type Shear and this can be used as a response.

But, stress and strain are not recommended for topology optimization.

Hi

Thank you very Much

But how about minimizing Compliance ( strain energy ) ( in Other Words maximizing stiffness) maybe i used wrong terminology .. I want to maximize strain energy to have Much Flexible structure ..but how..

I want to learn on solutıon of simple rectangular domain to get idea or methods to increase the flexibility of my design With best topology ( material distribution)

Thanks

Hi,

You can use compliance as a objective response which can be defined for entire structure or property or material and you can try with volume fraction as an optimization constraint.

Hi thanks;

As far as i searched minimizing Compliance gives stiffer structure.. So should i minimize Compliance? To have Much more Flexible structure ( beam for example)

Thanks

Regards

Sorry should i maximize Compliance ? Does it work?

Hi,

Yes, maximizing compliance will result in a less stiffer structure.
