Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]
, 2013 This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

Impact of Indentation in Programming [PDF]
International Journal of Programming Languages and Applications, 2013 In computer programming languages, indentation formats program source code to improve readability. Programming languages make use of indentation to define program structure .Programmers use indentation to understand the structure of their programs to human readers.

Micromechanical Characterization of Hydrogels Undergoing Swelling and Dissolution at Alkaline pH
Gels, 2017 The swelling of polyelectrolyte hydrogels usually depends on the pH, and if the pH is high enough degradation can occur. A microindentation device was developed to dynamically test these processes in whey protein isolate hydrogels at alkaline pH 7–14. At

Indentation into polymeric foams
International Journal of Solids and Structures, 2010 The effects of the nose shape of rigid indenters on the indentation behaviour of polymethacrylimide(PMI) and polyetherimide(PEI) foams with different densities are investigated. Experimental results show that indentation resistance depends on the geometry of the indenter and the density of the foam. Analytical models based on the deformation mechanisms

Mechanical properties of Al2O3 inverse opals by means of nanoindentation [PDF]
, 2016 In order to understand the mechanical behaviour of Al2O3 inverse opals, nanoindentation techniques have been implemented in material layers with three different microstructures, in terms of hollow or polystyrene spheres, with Al2O3 shells of distinct ...

Toughness of Bulk Metallic Glasses
Metals, 2015 Bulk metallic glasses (BMGs) have desirable properties like high strength and low modulus, but their toughness can show much variation, depending on the kind of test as well as alloy chemistry.
