The development of new materials and devices for flexible electronics depends crucially on the understanding of how strain affects electronic material properties at the nano-scale. Scanning Kelvin-Probe Microscopy (SKPM) is a unique technique for nanoelectronic investigations as it combines non-invasive measurement of surface topography and surface electrical potential. Here we show that SKPM i...

numerical methods such as boundary element and finite element methods are widely used for the stress analysis in solid mechanics. this study presents boundary element method based on the displacement discontinuity formulation to solve general problems of interaction between hydraulic fracturing and discontinuities. the crack tip element and a higher order boundary displacement collocation techn...

The focus of this study is the thermomechanical characterization and comparison between two different shape memory alloys (SMAs) quantifying the effect of plastic strain on the transformation characteristics of SMA actuators. In this study, the thermomechanical response and transformation characteristics of a NiTiCu and a NiTi SMA are studied as a function of the induced plastic strain for four...

This investigation examined transactional relations across contextual strain, parenting quality, and child adjustment in 209 mothers and children at 24, 42, and 72 months of age. Independent ratings of mothers' stressful life events, social support, and relationship quality provided an objective measure of maternal contextual strain. Observers evaluated parenting quality during parent-child int...

Peierls distortion path was proved experimentally for dense ZnO nanoparticles prepared by static compression. Electron irradiation caused rock salt (R) to wurtzite (W) transition, following preferential (111)(R)//(0111)(W); [011](R)//[1213](W) and then transformation strain induced (111)(R)//(1011)(W); [011](R)//[0111](W). The two relationships can be rationalized by specified extent of chair- ...
