Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Dynamic buckling of laminated composite stringer stiffened CFRP panels under axial compression

MATEC Web of Conferences, 2018
In this work, the dynamic buckling of stiffened panels is evolved numerically through a nonlinear incremental expression through making use of a specific time integration procedure via the finite element software program.

Numerical analysis of the effect of torispherical head on the buckling of pressure vessel

Engineering Transactions, 2014
The shape of end heads of a pressure vessel is usually torispherical. Buckling of this head is one of the most important points for designing of pressure vessels. This subject has been studied extensively since last years. In this field, the experimental

Bistable polar-orthotropic shallow shells [PDF]

Royal Society Open Science, 2019
We investigate stabilizing and eschewing factors on bistability in polar-orthotropic shells in order to enhance morphing structures. The material law causes stress singularities when the circumferential stiffness is smaller than the radial stiffness (β <

From In‐Silico Optimized Microfabrication to Experimental Validation: Engineering a Tridimensional Epi‐Intraneural Interface

Advanced Functional Materials, EarlyView.
An epi‐intraneural interface is developed through in silico optimization and a novel tridimensional microfabrication pipeline. The device integrates penetrating and epineural contacts on a flexible substrate. Mechanical, electrochemical, and in vivo testing in rat and pig reveal robust implantation, low‐threshold activation, and site‐dependent ...

Study on helical post-buckling of motional coiled tubing in horizontal wells

Journal of Petroleum Exploration and Production Technology
Coiled tubing is widely used in oil and gas operations. However, the long coiled tubing may undergo sinusoidal or helical buckling deformations, and even lock-up, leading to property damage and serious accidents.

Buckling and strength analysis of panels with discrete stiffness tailoring [PDF]

, 2019
Continuous variation of stiffness across flat plates has been shown, theoretically, to improve buckling performance by up to 60%. However, steered fibre manufacturing methods cannot achieve the minimum radius of curvature required for improvement whilst ...
