Uniaxial Compression Test of BCC (with waved struts) Lattice Structure (Mechanical Metamaterial).

Описание к видео Uniaxial Compression Test of BCC (with waved struts) Lattice Structure (Mechanical Metamaterial).

Here is a uniaxial compression test of a famous lattice structure (BCC) with waved struts, which is produced by additive manufacturing (3d Printing) of PLA material. Moreover, I had an idea to investigate the effect of waved struts on the mechanical properties of lattice structure, as the first result, the structure showed up some local shear fracture and eliminate the buckling barreling compression method. More results are presented in the article and ill add it to this post after publication.
