Introduction

This example uses a Design of Experiments (DOE) to explore the response of a loaded cantilever beam while varying its geometry. The example also illustrates how you can find the optimal design after specifying objectives from among the responses. For example, the maximum displacement of the beam is a response to the loading, and you might specify that an objective is to minimize the maximum displacement.

Problem Description

You will create a model of a simple cantilever beam. The initial dimensions of the beam are a height of 20 mm (h), a width of 30 mm (b), and a length of 200 mm (L), as shown below:



The beam is fixed at one end, and you will apply a vertical load of 10,000 N to the free end (P). The beam is made of steel, which is assumed to be an isotropic and linear elastic material with a Young's modulus of 200 GPa, a Poisson's ratio of 0.3, and a density of 7800 kg/m3.

You create a physics simulation that calculates the response of the beam to the fixed load. You then include the physics simulation in a Process Composer workflow and drive the simulation from a DOE that varies the dimensions of the beam (height, width, and length) between specified limits. The DOE studies the effect of varying the dimensions on the mass of the loaded beam, the peak von Mises stress, and the maximum displacement, as shown below:
