Abstract This work evaluates and revisits elements from the depth-sensing indentation literature by means of carefully chosen practical cases, simulated numerically compared to experiments. The aim is not provide a comprehensive study, but close series debated subjects, which constitute major sources inaccuracies in evaluation data practice, with help illustrative examples. First, own examples ...

Multicomponent formulations coupled with complex processing conditions govern the final properties of photopolymerizable dental composites. In this study, a single test substrate was fabricated to support multiple formulations with a gradient in degree of conversion (DC), allowing the evaluation of multiple processing conditions and formulations on one specimen. Mechanical properties and damage...

We employed depth-sensing nanoindentation to produce ordered arrays of indents on the surface of 50 nm-thick Au(Fe) films deposited on sapphire substrates. The maximum depth of the indents was approximately one-half of the film thickness. The indented films were annealed at a temperature of 700 °C in a forming gas atmosphere. While the onset of solid-state dewetting was observed in the unpertur...

PURPOSE Palpation is used most commonly to assess tissue stiffness despite its well-known deficiencies. As an improvement, a mechanical technique known as ultrasonic indentation has been proposed. The purpose of this study was to compare the accuracy of 3 ultrasonic indentation techniques in quantifying bone displacement in a specially constructed tissue simulator. METHODS Three ultrasonic in...

Introduction Currently, the load-bearing capacity of tissueengineered cartilage is insufficient. Inducing sufficient collagen content with an arcade-like architecture is a solution. Recently, sliding indentation was proposed for this puropse. However, it was only initially explored and further optimization may yield significantly better results. The aim of this study is to investigate in-silico...
