Based on the gradient hierarchical distribution of vascular bundles bamboo, a multicellular column (GHMC) evolved from spatial folding was proposed. Crashworthiness analysis GHMC carried via Abaqus/Explicit. Results show that proposed has better energy absorption ability compared with square tube under same thickness or mass. The wavelength is significantly decreased and it can produce more number folds tube. Under condition mass, peak crushing force decreases meanwhile its increase by 10.1%...
Combining reentrant honeycomb (RH) and double arrowhead (DAH), the (RDAH) is proposed. The deformation modes compression behavior of RDAH are numerically simulated compared with RH. results show that has a better specific energy absorption SEA than RH regardless low velocity or high impact. Compared RH, increased by 9.4% under an impact 1 m/s 24.4% 100 m/s. mechanical properties different velocities relative densities were further discussed, empirical formulas established based on mode map...
Drawing inspiration from the branching structure of trees, a novel Tree-like Hierarchical Multi-cellular Bi-tube (THMBT) has been devised. This design merges hierarchical distribution traits tree branches with superior crashworthiness double square tube structures. Utilizing validated finite element model, this study investigates THMBT, examining impacts wall thickness, bifurcation angle, and length on its performance. The Simplified Super Folding Element theory is employed for theoretical...
Methamphetamine (METH) is an illicit drug that causes neurodegenerative effects in humans. In rodents, METH induces apoptosis of striatal glutamic acid decarboxylase (GAD) -containing neurons. This paper provides evidence METH-induced cell death occurs consequent to interactions ER stress and mitochondrial pathways. Specifically, injections are followed by almost immediate activation proteases calpain caspase-12, events consistent with drug-induced stress. Involvement was further supported...
Hierarchical design and gradient have been shown to improve the crashworthiness of structures. However, fewer studies combine two. Therefore, this study combines two a novel double-gradient hierarchical hexagonal tube (DGHHT) based on (HT). According different axial gradients, they are divided into DGHHT-1 DGHHT-2. The under multiple loads was studied by finite element simulation. Firstly, reliability model is validated experimental results. Secondly, compared with single-gradient tubes...
To improve the energy absorption characteristics of thin-walled structures under oblique loads, a new hexagon hierarchical gradient structure (HHGS) was designed in this work, which inspired by fractal tree nature. The crashworthiness loads systematically studied numerical simulation method. force-displacement curve is different from that conventional tubes axial loads. Crashworthiness comparisons show can significantly reduce initial peak forces and maintain good deformation patterns...
Inspired by the tree fractal structure, a novel hexagonal hierarchical gradient tube with axial variable thickness (HHGAVT) is proposed and its crashworthiness performances are systematically investigated. Results show that when variation coefficient of wall k > 0, peak crushing force (PCF) HHGAVT will significantly decrease meanwhile energy absorption maintains at high level compared referenced structures under same mass. When PCF CFE have absolute advantage uniform tube. The performance...
