Abstract The rudder of an airplane is fabricated as a sandwich panel and can potentially be damaged by hail ice. The dynamic responses of a CFRP/Nomex sandwich panel with barely any visible core damage under multi-angle impact of an ice sphere at various velocities are researched experimentally and by using numerical simulations at the mesoscale. The results show that the honeycomb core represents three types of failure modes: wrinkling, fracture of cell walls, and debonding of cell walls at the...

Abstract Hail ice inevitably contains entrapped air bubbles in nature. The dynamic mechanical properties of ice are highly affected by the dimension, distribution and amount of the entrapped air bubbles. The bubbles in ice neither could be manufactured by man-made or obtained from nature with controllable amount and distribution, nor simulated by classic FEM in mesoscale due to its small size. A stochastic algorithm has been proposed as the sparse distribution mechanism of air bubbles in ice to ...

Abstract Large scale aircraft composite panels can be damaged by hail ice in high speed ductile impacts (without penetration by sharp shape) and predicting the damage modes and failure mechanisms under these complex boundaries and loading conditions poses a unique challenge. Thus, the dynamic behavior and failure of stringer-stiffened curved carbon/epoxy composite panels impacted by hail ice at two classic locations (mid-bay of impact type I and mid-flange of impact type II) with different veloc...

Abstract A novel sparsity-based stochastic pooling which integrates the advantages of max-pooling, average-pooling and stochastic pooling is introduced. The proposed pooling is designed to balance the advantages and disadvantages of max-pooling and average-pooling by using the degree of sparsity of activations and a control function to obtain an optimized representative feature value ranging from average value to maximum value of a pooling region. The optimized representative feature value is em...

Abstract The dynamic tensile properties of natural hybrid fibers reinforced composites with components of recycled-office-paper (ROP) fibers and old corrugated cardboard (OCC) fibers at different proportions are investigated by using an aluminum split Hopkinson tension bar (SHTB) at the strain rates ranging from 300/s to 1500/s. The influence on strain–stress relationship and strength by changing its component proportions are tested under quasi-static and dynamic loading. It is observed that the...

Abstract A series of experiments on damage detection of large-diameter (88 mm diameter) pipe with and without liquid by guided waves have been conducted. Two types of liquid as water and machine oil are chosen to fill in pipe for detecting the influence of filler. The influences of liquid types on guided wave propagation, dispersion and attenuation characteristics have also been studied. The mode conversion phenomenon of reflection waves exists regardless filling state of pipe, but it is most se...

Peptide amphiphiles (PAs), functionalized with alkyl chains, are capable of self-assembling into various nanostructures. Recently, PAs have been considered as ideal drug carriers due to their good biocompatibility, specific biological functions, and hypotoxicity to normal cells and tissues. Meanwhile, the nanocarriers formed by PAs are able to achieve controlled drug release and enhanced cell uptake in response to the stimulus of the physiological environment or specific biological factors in th...

Bone tissue engineering uses the principles and methods of engineering and life sciences to study bone structure, function and growth mechanism for the purposes of repairing, maintaining and improving damaged bone tissue. Scaffolds not only provide structural support for stem cells in cell adhesion and proliferation and bone formation, but also serve as a microenvironment for guiding stem cell differentiation and tissue regeneration and for controlling tissue structure. This review presents the ...

Abstract Worker honeybee is well-known for its stinger with microscopic backward-facing barbs for self-defense. The natural geometry of the stinger enables painless penetration and adhesion in the human skin to deliver poison. In this study, Apis cerana worker honeybee stinger and acupuncture microneedle (as a barbless stinger) were characterized by Scanning Electron Microscope (SEM). The insertion and pull process of honeybee stinger into rabbit skin was performed by a self-developed mechanical...

The dynamic compressive behavior of ice is investigated using a large-sized (37 mm in diameter) modified aluminum split Hopkinson pressure bar (SHPB) with pulse shaper at the strain rate from 500 s-1 to 1200 s-1. A series of relatively stable experimental results of dynamic compressive strength versus strain rate and a linear fitting curve have been obtained by controlling data scatter within 25%. The composition of incident wave has been discussed. The effects of pulse shaper diameter and veloc...
