We report for the first time the results of tensile stress testing of thin film conductive structures patterned by stencil lithography on a PI substrate. The goal of this investigation is to determine the effects that mechanical deformation occurring in re ...
The purpose of this review is to discuss the development and the state of the art in dynamic testing techniques and dynamic mechanical behaviour of rock materials. The review begins by briefly introducing the history of rock dynamics and explaining the sig ...
The edge strength of glass is influenced by the size of the surface (near the edge) which is subjected to tensile stresses. To quantify this size effect, 8 series of single layer annealed glass beam specimens (as-received glass) were subjected to in-plane ...
The invention concerns a pressure transducer comprising a deflecting membrane, said membrane comprising two piezoresistors (10, 11) of different types, said piezoresistors being arranged such that a same stress or a same strain is applied on said piezoresi ...
Drying shrinkage is modeled at a microscale as a two-stage process of deformation and evacuation of a two-tube vessel system, based on porosimetry evolution. In the first stage water flow is driven by an external evaporation flux. Flow is associated with a ...
The first reported tensile semi-solid stress/strain data for as-cast magnesium alloy Mg Al3 Zn1 are provided. The results show that the maximum tensile stress at the solidus temperature (460 degrees C) was 13 MPa. Furthermore, this alloy has no ductility a ...
Stencil lithography (SL) is a shadow mask technique which allows parallel, resistless, micro- and nano- patterning of material through apertures created in a membrane (stencil) onto a substrate. The stencils are usually made of LPCVD low-stress SiN due to ...
In this study, we present the results and implications of an experimental study into the effect of gold-ion implantation on the actuation performance of ionic-type conducting polymer actuators, represented here by cantilevered tri-layer polypyrrole (PPy) a ...
Mean index changes up to 2.2 × 10-3 were demonstrated in hydrogen loaded germanium free Bi-Al-doped silica fibers. Tensile stress changes indicate a contribution of compaction to the total index change. ...
Refractive index changes up to 2.5 × 10-3 were demonstrated in H2-loaded germanium free Bi-Al-doped silica fibers using both ArF excimer and cw-Ar+-244 nm lasers. Tensile stress changes indicate clear contribution of compaction to the total index change. ...
