Topology Optimization Used to Make Lighter Plastic Parts

Kanto Auto Works, Ltd. is a core member of the Toyota Group, developing and producing Toyota vehicle bodies. The company’s organic-material engineering department evaluates and develops plastic parts to be used in vehicle bodies.

Do It consists of a written exercise and model that can be opened in HyperMesh which allows you to perform the exercise on your own. Some sections will also contain interactive guides to provide a detailed description of the different options contained within a panel or browser.
