Lawrence Livermore National Laboratory (LLNL) researchers have designed a new class of 3D-printed lattice structures that are lightweight and highly stiff, a combination that is not supposed to be ...

image: MIT researchers used kirigami, the art of Japanese paper cutting and folding, to develop ultrastrong, lightweight materials that have tunable mechanical properties, like stiffness and ...

To find the weak link of the structural stiffness is important to improve machine tool stiffness. However, how to overcome the static deformation with difficulty acquisition is a difficult problem in ...
