rounding the corners in an electromechanical fem model
... One standard method to overcome these convergence problems consists in rounding off the corners6 . In that case the singularity is smoothed, thus the charge peak at the corner remains bounded, hence there is a finite force peak at the corner. However one big disadvantage of a rounded corner is relat ...

Electroactive polymers
Electroactive polymers, or EAPs, are polymers that exhibit a change in size or shape when stimulated by an electric field. The most common applications of this type of material are in actuators and sensors. A typical characteristic property of an EAP is that they will undergo a large amount of deformation while sustaining large forces.The majority of historic actuators are made of ceramic piezoelectric materials. While these materials are able to withstand large forces, they commonly will only deform a fraction of a percent. In the late 1990s, it has been demonstrated that some EAPs can exhibit up to a 380% strain, which is much more than any ceramic actuator. One of the most common applications for EAPs is in the field of robotics in the development of artificial muscles; thus, an electroactive polymer is often referred to as an artificial muscle.
