Shape Memory Polymer‐Based Flexible Pressure Sensor for Real‐Time Venous Thrombosis Monitoring
Advanced Materials Interfaces, EarlyView.A shape‐memory tubular flexible pressure sensor with a 100‐mesh microstructured SMP‐PLA/MWCNTs sensing layer was developed for PICC‐mounted monitoring of thrombosis‐related pressure changes. The sensor combines high sensitivity (204 kPa−1), a fast response time (28 ms), and conformal catheter fixation and was validated by hydrostatic and ex vivo ...

Advanced Materials Interfaces, EarlyView.A controlled layer‐by‐layer growth process integrates conjugated metal‐organic framework thin films onto a hierarchical 3D laser‐induced graphene scaffold. When incorporated into an extended‐gate field‐effect transistor configuration, this synergistic hybrid platform achieves robust aptamer immobilization, driving highly selective, picomolar‐level ...

Spherically symmetric thin walls
Physical Review D, 1991Assuming a continuous ansatz for the metric we solve the Einstein equation for a thin wall directly by using the method of distributions.

Abstract The ironing of thin walled cans has been analysed using the slab method and FEM. The results show that there exists a critical reduction ratio at which the ironing process may become unstable (or not self-centring). The results obtained show that the critical reduction ratio is heavily influenced by the geometry of the ironing die (semi-die ...

There exists a great variety of possible buckling modes of thin-walled bars. Besides Euler’s buckling and lateral buckling we mention here, first of all, torsional buckling, and a combination of these phenomena. The above buckling modes, called jointly “the overall buckling”, may be investigated under the assumption of undeformable cross-sectional ...

On the Modelling of Thin Walled Beams
2015Thin Walled Beams (TWBs) can be modelled as three dimensional bodies, shell, folded plates or, as their shape seems to suggest, as one dimensional continua. In the last case it must be pointed out that, also in the framework of the linear elasticity, the Saint-Venant solutions can not apply, in most of the cases, to those structures.

AbstractThe fundamental concepts of alloy fluidity and liquid flow are examined to highlight the main problems in the production of thin walled castings and to identify areas where research is required. Subjects covered include the problems of entrained oxides of varying degrees of severity, and the introduction of the concept of ‘old’ and ‘new’ oxide ...

Typical aeronautical structures involve light-weight, thin-walled, beam-like structures that must operate in a complex loading environment where combined axial, bending, shearing, and torsional loads are present. These structures may consist of closed or open sections, or a combination of both.

Chapter 4 addresses the behavior of rectilinear, thin-walled beams in torsional response. First, it shows how open and closed profiles are affected by generally developed warping in a thin-walled section while considering the profile contour to be undeformable.
