Abstract

Due to the development of additive manufacturing technology, a lot of complex 3D cellular structures can be manufactured. Therefore, there has been a significant growing interest in 3D printing cellular structures due to their excellent mechanical properties. As one type of periodic 3D cellular structure, triply periodic minimal surface (TPMS) lattice structure is investigated widely because it is found to have higher energy absorption capacity than the traditional 3D cellular structure. However, the previous investigation on TPMS structure was mainly implemented by simulation or experiment study. There is little theoretical prediction about the energy absorption properties of the TPMS structure. Hence, the theoretical prediction for TPMS structure is carried out in this study using the folding element theory together with the principle of conservation of energy. Three TPMS structures under axial crushing loading are theoretically analyzed. According to the comparison results, it is found that the theoretical prediction of mean crushing stress is in good agreement with both experimental and numerical simulation results. The theoretical prediction method can clearly reveal the influence rule of the structural parameters on the energy absorption of the TPMS structure. Moreover, the energy absorption of TPMS can be calculated conveniently by the theoretical prediction. Thus, the theoretical reference of TPMS cellular structures for its engineering application is provided.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
