WEB Instabilities and pattern formations in soft compositesWednesday (23.09.2020) 17:35 - 17:50 S: Structural Materials 2 Part of:
Elastic instability is a fascinating phenomenon playing an important role in pattern formations in soft biological systems. The phenomenon also has been actively used to design new (meta-) materials with switchable microstructures, properties, and functions .
Here, we investigate the elastic instability phenomenon in soft heterogeneous materials. These deformable composites typically combine soft deformable matrix and stiffer phase (such as fibers or inclusions). Figure 1 shows the experimentally observed wavy patterns forming in (a) soft 3D printed laminates  and (b) 3D-fiber composites , (c) twining pattern in particulate composites , and (d) auxetic microstructure transformations in inclusion-matrix-void soft systems .
