Topology optimization, SIMP

[peta1234]

As I know Abaqus uses SIMP method for topology optimization. I’m new to this topic, so I’m trying to learn. SIMP method (solid isotropic material with penalization) can I use this method when optimizing a concrete beam? Concrete is anisotropic material, so my question is, is the method valid for anisotropic material? If not, then I need to find another software? It is not possible to change optimization method in Abaqus

 

[FEA way]

Orthotropic and fully anisotropic materials are supported for topology optimization in Abaqus. Check the book "Topology Optimization. Theory, Methods, and Applications" by Bendsoe and Sigmund if you want to know kore about the theory behind this.

How do I change the method then, or is it not necessary? At the moment, the option is, SIMP and ramp.

 

[FEA way]

It shouldn’t be necessary, I would use the default setting.

ICYC... Euler... an earlier 'engineer' (actually a smart individual) that was largely responsible for determining column buckling load back in the 1700s was largely responsible for initiating the mathematics of topology with his solution to the Königsberg Bridge Problem. His approach led to 'the mathematics of spaces'.
