We develop a new high-order method for Eulerian simulations of solids undergoing large, elastic–plastic deformations. Thermodynamically consistent constitutive relations of classical hyperelasticity are used to describe the behavior of solids, liquids and gases in a unified manner. Two kinematic formulations, one based on the inverse deformation gradient tensor, and a second based on the symmetric...
This paper proposes two assistive mobility devices for individuals with visual impairments. These devices use ultrasound technology for the detection of the obstacle distance and a vibration motor - based tactile interface system that generates different vibration patterns as a function of obstacle distance to alert the user. The main device consists of an ultrasound sensor and associated control...
