Evolutionary Growth Approach

Mimic how bones / plant roots add material to regions under high stress and reduce material where there is small stress
• Apply load to structure

• Apply load to structure

• Determine stress in all members
- In each member Area_new = Area_old * σ / σ_max

• Good for stress problems but difficulties when there are other parameters (e.g. buckling / flutter / etc)
