A Computational Model for Surface Welding in Covalent Adaptable Networks Using Finite Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Covalent adaptable network (CAN) polymers can rearrange their macromolecular network by bond exchange reactions (BERs), where an active unit attaches to and then replaces a unit in an existing bond and forms a new bond. ...
Three-Dimensional-Printed Multistable Mechanical Metamaterials With a Deterministic Deformation Sequence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multistable mechanical metamaterials are materials that have multiple stable configurations. The geometrical changes caused by the transition of the metamaterial from one stable state to another, could be exploited to ...
Level Set Topology Optimization of Printed Active Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multimaterial polymer printers allow the placement of different material phases within a composite, where some or all of the materials may exhibit an active response. Utilizing the shape memory (SM) behavior of at least ...
