Mechanical properties of Al2O3 inverse opals by means of nanoindentation [PDF]

open access: yes, 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 ...

Temperature-Induced Internal Stress Influence on Specimens in Indentation Tests

open access: yesMicromachines, 2022
The factors affecting the internal stress of specimens during indentation tests were investigated by finite element analysis (FEA) modelling. This was carried out to gain a qualitative understanding of the test errors introduced by the temperature ...

Depth-sensing indentation tests in studying plastic instabilities [PDF]

open access: yes, 2004
This review surveys the phenomenon of plastic instabilities occurring in depth-sensing indentation measurements. Investigations presented focus on the characterization of Portevin-Le Chatelier type instabilities observed in different metal alloys during ...

Twinning and Slip in Zinc by Indentation [PDF]

open access: yes, 1968
Observations of twinning and slip deformation caused by indentation of zinc reveal that extensive slip on the basal and second-order pyramidal systems takes place at loads up to 5 kg.

Indentation of ellipsoidal and cylindrical elastic shells [PDF]

open access: yes, 2012
Thin shells are found in nature at scales ranging from viruses to hens’ eggs; the stiffness of such shells is essential for their function. We present the results of numerical simulations and theoretical analyses for the indentation of ellipsoidal and ...

Effect of Velocity and Contact Stress Area on the Dynamic Behavior of the Spinal Cord Under Different Testing Conditions

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Knowledge of the dynamic behavior of the spinal cord under different testing conditions is critical for our understanding of biomechanical mechanisms of spinal cord injury. Although velocity and contact stress area are known to affect external mechanical
