An Investigation on Shape Morphing by Modulus Variation: Forward Approach

Journal of Engineering, Volume 2014, Issue 1, 2014., 2014
Structural shape deformation, in its conventional way, includes applying forces to a fixed‐compliance structure to deform it to certain shapes. Rather than addressing shape control in the established way (applying forces to elastically or plastically deform a structure), this work studies the use of shape morphing, which involves combining applied ...

Investigation of the electroplastic effect using nanoindentation

Materials & Design, 2019
A promising approach to deform metallic-intermetallic composite materials is the application of electric current pulses during the deformation process to achieve a lower yield strength and enhanced elongation to fracture.

A Dislocation Perspective on Strength and Toughness in Ceramics

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Temperature Control in Spark Plasma Sintering: An FEM Approach

Journal of Metallurgy, Volume 2010, Issue 1, 2010., 2010
Powder consolidation assisted by pulsed current and uniaxial pressure, namely, Spark Plasma Sintering (SPS), is increasingly popular. One limitation however lies in the difficulty of controlling the sample temperature during compaction. The aim of this work is to present a computational method for the assembly temperature based on the finite elements ...

Electric‐Current‐Induced Phase Transformation in Cu6Sn5 Below Its Equilibrium Transition Temperature

Advanced Science, Volume 13, Issue 41, 22 July 2026.
Electric current induces a monoclinic‐to‐hexagonal phase transformation in Cu6Sn5 at a measured bulk temperature of ∼120°C, below the equilibrium transition temperature. Ex situ synchrotron x‐ray diffraction, TEM, and matched thermal controls show that current stressing promotes the formation of a retained hexagonal η‐phase post‐stress state not ...

Dislocation response to electric fields in strontium titanate: A mesoscale indentation study

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Dislocations in perovskite oxides have drawn increasing research interest due to their potential for tuning functional properties of electroceramics. Open questions remain regarding the stability of dislocations under strong externally applied electric fields. In this study, we investigate the dielectric breakdown strength of nominally undoped
