Mechanical analysis of indentation experiments with a conical indenter [PDF]
Philosophical Magazine, 2006 The finite element method was used to study the pyramidal indentation of elastic perfectly plastic (EPP) solids. The ratio of the effective elastic modulus, E*, to the flow stress, σ0, ranged from 2.79 (quasielastic solid) to 2790 (quasirigid perfectly plastic (quasi-RPP) solid).

Failure modes of composite sandwich beams [PDF]
Theoretical and Applied Mechanics, 2008 A thorough investigation of failure behavior of composite sandwich beams under three-and four-point bending was undertaken. The beams were made of unidirectional carbon/epoxy facings and a PVC closed-cell foam core.

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 ...

Experimental analysis of indentation morphologies after spherical indentation [PDF]
Materials Research, 2013 Indentation morphologies depend on the mechanical properties of materials, especially the strain-hardening exponent and yield strength-to-elastic modulus ratio. Hernot et al.¹ described a model that can be used to obtain the indentation morphology index from properties determined in tensile tests.
