Time Domain Analysis of Dielectric Relaxation
When a material is subjected to a sudden change in electric field, the polarization of the material takes a finite time to respond – this phenomenon is referred to as dielectric relaxation. Dielectric relaxation is critical to understanding the important analytic technique of impedance ... Read More
Stress/Strain Analysis of a Nitinol Self-Expanding Stent
Nitinol self-expanding stents are most commonly used to widen the passage of a restricted blood vessel. Unlike balloon-expandable stents, nitinol allows the stent to recover large strains caused by mechanical stresses due to its superelasticity. Self-expanding stents are first crimped to ... Read More
