Publisher: American Society of Mechanical Engineers
Paper No: SMASIS2022-89036
... Abstract 4D printing, as an emerging technology, fabricates structures with smart materials which deform under stimuli. The bilayer structure is special in 4D printing that has lots of capabilities such as self-folding. The prediction of bilayer structure deformation in the design phase is very...
