Outline of Final Research Achievements

In this study, mechanical properties of micro-lattice structures such as bending toughness, vibration properties, impact crushing capacity, heat management and sound absorption response are investigated by using numerical simulations and experiments. The main purpose of these investigations is to explore the possibility of application for lattice structures. There is a lot of flexibility in the design of lattice structures. Based on this study, it is clarified how much performance can be achieved. Also, the amount of imperfection observed in a lattice block manufactured by selective laser metal melting machine is measured, and the relationship between the accuracy of dimension and laser condition is investigated. In addition, a structural optimization of lattice structure by minimizing the compliance as an object function is conducted under the formable condition. Consequently, an important design guideline of manufacturing based on selective laser metal melting can be clarified.
