Topology Design of Structures under Load Uncertainties
The optimal topology design is defined as an optimization problem of material distribution. The material
densities of finite elements serve as variables and the maximum stiffness is defined as the objective function. The
uncertainties of loading are considered. The uncertainties are declared using the truncated Gaussian distribution as a
statistical distribution function.The Monte Carlo simulation is applied. The probability analysis demands essentially a
repetitive solution.The optimization procedures also generally use repeated numerical procedures with parameter
changes.The contribution proposes topology optimization guided by the probability procedure. All analyses were performed
in ANSYS.Generally, the obtained results are robust and usable in practice.
