Structural stress minimization
Challenges that we enjoyed solving
Stiffness maximization will not necessitate stress minimization. Compliance function is being used successfully for the past three decades associated with SIMP method.Stress can be addressed as an effective objective function to minimize the singularity topography (stress concentration parts). Using finite element as discretization method for topology optimization is imposing the use of nodal displacement to calculate the strain then the stress. The nodal displacement effect will be discussing later in this chapter. The stress itself, they are the direct translation of force action with related nodal displacement. The translation is done in terms of stiffness matrix and displacement matrix. In the core of this matrices multiplication is the property matrix that is model in term of the artificial density function.
