An investigation of non-planar austenite-martensite interfaces [PDF]
arXiv, 2013 Motivated by experimental observations on CuAlNi single crystals, we present a theoretical investigation of non-planar austenite-martensite interfaces. Our analysis is based on the nonlinear elasticity model for martensitic transformations and we show that, under suitable assumptions on the lattice parameters, non-planar interfaces are possible, in ...

A Wearable Soft Actuator for Directional Tactile Stimulation: Design and Testing
Advanced Intelligent Systems, EarlyView.A wearable actuator able to produce directional tactile stimulation is obtained by embedding a planar shape memory spring in silicone matrix. The matrix is designed taking into account skin characteristics and leveraging its multifunctionality: it acts as a bias load, improves the thermal behavior of the spring and wearability.

4D Printing of Composite Thermoplastic Elastomers for Super‐Stretchable Soft Artificial Muscles
Journal of Applied Polymer Science, EarlyView.ABSTRACT This study explores the development of soft, super‐stretchable artificial muscles by 4D printing of composite thermoplastic elastomers. A propylene‐based elastomer, combined with carbon black (CB) nanoparticles, is utilized to develop nanocomposite elastomers with enhanced mechanical properties.

Comparative study of hydrogen embrittlement resistance between additively and conventionally manufactured austenitic stainless steels [PDF]
arXiv, 2020 Hydrogen embrittlement in 304L (18wt.% Cr, 8-10wt.% Ni) austenitic stainless steel (ASS) fabricated by laser powder-bed-fusion (LPBF) was investigated by tensile testing after electrochemical hydrogen pre-charging and compared to conventionally available 304L ASSs with two different processing histories, (i) casting plus annealing (CA) and (ii) CA plus
