Swelling-induced deformations: a materials-defined transition from macroscale to microscale deformations

Swelling-induced deformations: a materials-defined transition from macroscale to microscale deformations.

Swelling-induced deformations are common in many biological and industrial environments, and the shapes and patterns that emerge can vary across many length scales. Here we present an experimental study of a transition between macroscopic structural bending and microscopic surface creasing in elastomeric beams swollen non-homogeneously with favorable . We show that this transition is dictated b...

Microchannel deformations due to solvent-induced PDMS swelling.

The compatibility of polydimethylsiloxane (PDMS) channels with certain solvents is a well known problem of soft lithography techniques, in particular when it leads to the swelling of the PDMS blocks. However, little is known about the modification of microchannel geometries when they are subjected to swelling solvents. Here, we experimentally measure the deformations of the roof of PDMS microch...

Application of Meshfree Methods to Numerically Simulate Microscale Deformations of Different Plant Food Materials during Drying

9 10 Plant food materials have a very high demand in the consumer market and therefore, improved food products 11 and efficient processing techniques are concurrently being researched in food engineering. In this context, 12 numerical modelling and simulation techniques have a very high potential to reveal fundamentals of the 13 underlying mechanisms involved. However, numerical modelling of pl...

Finite Plane Strain Deformations of Rubberlike Materials

A finite element program capable of analysing finite plane strain deformations of incompressible rubberlike (Mooney-Rivlin) materials has been develop~d. Two problems, namely a long wall loaded uniformly in two directions and a thick-wall cylindrical pressure vessel loaded internally, have been solved. The computed values of displacements, strains, stresses and hydrostatic pressure agree very c...
