TL;DR: In this paper, the authors investigated the mechanical static compression behavior of 316L stainless steel micro-lattice materials manufactured using selective laser melting method and found that the stiffness and strength of these materials are quite close to experiments.

TL;DR: In this paper, three types of three-dimensional lattices based on triply periodic minimal surfaces were examined with a combination of experimental and computational methods and the results can be used to create better informed lattice designs for a range of mechanical and biomedical applications.

TL;DR: In this paper, the methods of analysis of data obtained from sub-micron indentation testing such as that performed on thin-film systems are discussed and the underlying theory behind the extraction of elastic modulus and hardness from the unloading load-displacement data obtained with spherical indenter and Berkovich pyramidal indenters is given in some detail.

TL;DR: In this article, the authors demonstrate why and how these elastic and plastic properties are correlated, in terms of the common structural origin underlying these mechanical behaviors in MGs, and identify the full icosahedral ordering as the key structural feature in the Cu-Zr MGs that controls not only the G and the G/B, but also the initiation of shear localization and the intrinsic plasticity.

TL;DR: This study demonstrates a novel and convenient technique to measure mechanical properties of hydrogel in a non-destructive, online and real-time fashion and can become a valuable tool for soft tissue engineering.
Abstract: We present a novel indentation method for characterizing the viscoelastic properties of alginate and agarose hydrogel based constructs, which are often used as a model system of soft biological tissues. A sensitive long working distance microscope was used for measuring the time-dependent deformation of the thin circular hydrogel membranes under a constant load. The deformation of the constructs was measured laterally. The elastic modulus as a function of time can be determined by a large deformation theory based on Mooney–Rivlin elasticity. A viscoelastic theory, Zener model, was applied to correlate the time-dependent deformation of the constructs with various gel concentrations, and the creep parameters can therefore be quantitatively estimated. The value of Young's modulus was shown to increase in proportion with gel concentration. This finding is consistent with other publications. Our results also showed the great capability of using the technique to measure gels with incorporated corneal stromal cells. This study demonstrates a novel and convenient technique to measure mechanical properties of hydrogel in a non-destructive, online and real-time fashion. Thus this novel technique can become a valuable tool for soft tissue engineering.
