In materials of all types, hysteresis and toughness are usually correlated. For example, a highly stretchable elastomer or hydrogel single polymer network has low toughness. The is commonly toughened by introducing sacrificial bonds, but breaking possibly reforming the bonds causes pronounced hysteresis. this paper, we describe principle that disrupt toughness-hysteresis correlation, achieving both high We demonstrate fabricating composite two constituents: matrix elastic modulus, fibers...
Many living tissues achieve functions through architected constituents with strong adhesion. An Achilles tendon, for example, transmits force, elastically and repeatedly, from a muscle to bone staggered alignment of stiff collagen fibrils in soft proteoglycan matrix. The align orderly adhere the strongly. However, synthesizing materials adhesion has been challenging. Here we fabricate polymer networks by sequential polymerization photolithography, attain adherent interface topological...
Flexible capacitive tactile sensors show great promise in personalized healthcare monitoring and human–machine interfaces, but their practical application is normally hindered because they rarely possess the required comprehensive performance, that is, high pressure sensitivity fast response within a broad range, structure robustness, performance consistency, etc. This paper aims to engineer flexible with highly ordered porous dielectric microstructures 3D-printing-based fully...
Abstract Microelectromechanical system (MEMS) microphones have achieved a great variety of applications like mobile phones and wearable devices due to their small volume, strong heat resistance high stability. However, the thermal stress induced by temperature variation in packaging service conditions greatly influences performance packaged MEMS microphone devices. We study development new type with dual-diaphragm using finite element method, focusing on geometrical parameter different...
The objective of this work is to study the large deflection geometrically asymmetric metal foam core sandwich beam under transverse loading by a fiat punch. A yield criterion proposed for structures, and then analytical solution fully clamped slender obtained, in which interaction bending stretching induced considered. Also, finite element (FE) analysis carried out. Comparisons with numerical results are presented good agreements found. effects factor, strength punch size on structural...
A yield criterion for physically asymmetric sandwich cross-sections is proposed in this paper. Using the criterion, analytical solutions large deflections of fully clamped slender beams transversely loaded by a flat punch at midspan are derived considering core strength effect and interaction bending axial stretching. Finite element (FE) method employed to predict deflection behavior beams. Good agreement achieved between predictions FE results. Effects factor, loading size also discussed....
