A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials

open access: yesAdvanced Engineering Materials, EarlyView.
This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...

Internally loaded cylindrical shells

Canadian Journal of Civil Engineering, 1982
Simply supported cylindrical shells under internal fluid and granular loading are investigated.A Fourier series solution is presented and results are shown for various shell geometries. Experimental data are shown to agree with the theoretical solutions.

Loads on internal spinal fixation devices

Der Orthopäde, 1999
The loads acting on internal spinal fixation devices were measured for different activities in ten patients using telemeterized bisegmental implants. The highest loads were found for walking and lateral bending of the upper body while standing. When bending forwards the upper body, the fixator loads were only slightly altered.
