TL;DR: In this paper, the mechanical behavior of silica aerogels was investigated with hardness, compression, tension and shear tests, with particular attention paid to the effects of processing parameters, including fiber-reinforcement.
Abstract: Aerogels are extremely low density solids that are characterized by a high porosity and pore sizes in the order of nanometers The mechanical behavior of silica aerogel was investigated with hardness, compression, tension and shear tests The influences of testing conditions, storage environment and age were examined, with particular attention paid to the effects of processing parameters, including fiber-reinforcement Good correlation was found between hardness and compressive strength over a wide range of processing parameters Increasing fiber reinforcement generally retarded shrinkage during fabrication and yielded smaller matrix densities for a given target density For a given fiber content, hardness, compressive strength and elastic moduli increased and strain at fracture decreased with increasing matrix density In the lower ranges of matrix density, fiber reinforcement increased strain at fracture and elastic moduli The mechanical response was also sensitive to environment and storage history With age, the compressive strength and elastic moduli increased while the strain at fracture decreased Tension and shear results indicate that shear strength of aerogels exceeds tensile strength which is consistent with brittle materials response

TL;DR: A two-dimensional finite element model of the human brain/ventricular system is developed and analysed under hydrocephalic loading conditions, and it is shown that the Young's modulus of the brain parenchyma used in previous studies corresponds to strain rates much higher than those present in hydrocephalus.

TL;DR: Mechanical properties of polyelectrolyte multilayer films were studied by nanoindentation using the atomic force microscope and spreading of smooth muscle cells on these substrates with pre-attached collagen proved to be highly dependent on film rigidity with stiffer films giving greater cell spreading.

TL;DR: The data indicated that the addition of polylactic acid can make homogeneous composites scaffold resist significantly higher stress and improve the elastic modulus of the composites, which can make them more beneficial for surgical applications.
