TL;DR: In this paper, a new transformation kinetics is derived which precisely predicts the compressive behavior of SMAs based on the following experimental results: drastic variation exists during transformation, and the plastic deformation is not ignored in compression; the deformation increases in proportion to the volume fraction of detwinned martensite; and the critical stress-temperature slopes largely increase and the slopes of the start and finish temperatures of each phase are not identical to each other.

TL;DR: In this article, a simple procedure for obtaining stress intensities is introduced in the estimation of the failure strength of anisotropic/isotropic bi-materials, where the expanded Stroh formalism is used to obtain asymptotic stress and displacement fields near the interface corner.

TL;DR: In this article, a micropatterning method was proposed to provide designed surface topography for adhesion strength enhancement, and an oxalic acid-based anodizing process was also applied after micro-scale patterning on aluminum surface to incorporate nanopores into the micro-atterned surface topology.

TL;DR: In this paper, an experimental study on the buckling and postbuckling control of a laminated composite beam with eccentrically embedded NiTi actuators is performed for the purpose of enhancing the critical buckling load.

TL;DR: In this article, an asymptotic solution for an interfacial crack in an anisotropic/isotropic bi-material is presented, and the applicability of the finite crack-extension strain-energy release rate is validated by comparing the critical finite extension energy release rate of double-lap joints with the measured fracture toughness of the interface.
