“…Instead, the effect of water would significantly affect the time-dependent mechanical behaviour of the tissue. Among the most recent studies on the tissue visco and poroelastic behaviour, see for example Paietta et al, (2011) or Olesiak et al (2010. In our work, since the aim of the study was the validation of the material model, which does not incorporate the evaluation of the time-dependent mechanical properties of the tissue, we did not tested the samples in hydrated conditions.…”

“…With the help of indentation tests carried out on different scales, a wide range of materials can be characterized: metals, alloys, ceramics, concrete [3] or even graded materials [4][5][6][7][8] and the test can also be applied to an actual structure without the need for cutting-out a specimen for tensile testing. Indentation-based assessment of material properties usually relies on the recorded force-displacement curve (P-h curve) [9][10][11][12] obtained in two main phases.…”

The conventional approach for the identification of the work hardening properties of a material by an indentation test usually relies on the force-displacement curve. However, finite element modeling of the indenter-specimen system is a complex task, and the unicity of the solution to the inverse problem of identifying material parameters using the force-displacement curve is not always guaranteed. Also, the precise measurement of the displacement of the indenter tip requires the determination of the indenter frame compliance and indenter tip deformation. To alleviate these problems, we propose in this work an approach based solely on the 3D indentation imprint shape measured after indenter withdrawal, rather than relying on the minimization of the pointwise discrepancy between the experimental and simulated indentation curve. We first build a mathematical "shape space" of indentation shapes in which a lower-dimensional manifold of imprints admissible according to a postulated material constitutive law is approximated. Then, we solve the inverse problem by using a series of predictor-corrector algorithms minimizing the distance between the estimated solution and the experimental imprint in this shape space. We finally apply the proposed approach to indentation tests using a spherical tip indenter on two different materials: a C100 steel specimen and a specimen of the AU4G (AA2017) aluminium alloy.

“…The understanding of measurement limitations and complexities has grown as the technique has been applied to bone. Researchers have investigated various effects of surface roughness [36], hydration [37], tip radius, contact depth, and contact area [38] on measured nanomechanical properties of bone. However, the viscoelastic properties of bone have been only recently explored [29,39].…”

Intrinsic Material Properties of Trabecular Bone by Nanoindentation Testing of Biopsies Taken from Healthy Women Before and After Menopause

Postmenopausal osteoporosis in women is characterized by an increase in bone fragility and risk of fracture. In addition to transmenopausal decline in three-dimensional trabecular bone architecture, changes in intrinsic material properties (local stiffness, damping, and hardness) may contribute to increased bone fragility. In this study, nanoindentation was used to quantify transmenopausal changes in the intrinsic properties of trabecular bone. Paired transilial biopsy specimens were used from a previously reported study in which bone biopsies were obtained from women prior to menopause (premenopausal, age 49.0 ± 1.9) and at 12 months past the last menstrual period (postmenopausal, age 54.6 ± 2.2). Elastic and viscoelastic material properties of the trabecular bone were measured using quasi-static and dynamic nanoindentation techniques, respectively. Paired Student's t tests (n = 15) were performed to assess the significance of the measured intrinsic properties. Trabecular bone microarchitecture is compromised in postmenopausal women, and although this loss is associated with a trend toward reduction in some intrinsic properties (storage modulus), we found no statistically significant changes in bone intrinsic properties between healthy pre- and postmenopausal biopsies in the quasi-static results and frequency-averaged dynamic results.
