Elastic modulus of the periodontal ligament

Biomaterials, 1997
This study used a two-dimensional finite element mesh of a lower first premolar to model two different tooth loading systems which measured either the vertical or the horizontal displacements of this particular tooth. The elastic modulus of the periodontal ligament was varied in the finite element model until the horizontal and vertical displacements ...

On The Elastic Modulus of Metallic Nanowires

Nano Letters, 2008
Previous atomistic simulations and experiments have attributed size effects in the elastic modulus of Ag nanowires to surface energy effects inherent to metallic surfaces. However, differences in experimental and computational trends analyzed here imply that other factors are controlling experimentally observed modulus changes.

Modulus of Elasticity

1983
In Part B, Section 3.1.8, relations to estimate the modulus of elasticity of concrete are summarized. In the following, the effect of type of aggregate and age at time of load application upon the modulus of elasticity, as well as on the modulus of deformation, will be illustrated.

Elastic modulus of hard tissues

Journal of Biomechanics, 2012
This work aims at evaluating the elastic modulus of hard biological tissues by considering their staggered platelet micro-structure. An analytical expression for the effective modulus along the stagger direction is formulated using three non-dimensional structural variables. Structures with a single staggered hierarchy (e.g.

Dynamic elastic modulus of ‘packable’ composites

Dental Materials, 2001
A new type of so-called 'packable', 'condensable' or 'mouldable' composite has been developed and aims at replacing amalgam for posterior restorations. The purpose of the present investigation was to study the dynamic elastic modulus of 12 packable composites, and to follow the evolution of this property following prolonged water absorption.Of each ...

Capability Analysis for Modulus of Elasticity and Modulus of Rupture

2013 10th International Conference on Information Technology: New Generations, 2013
Sawn softwood timber is used as a structural component in house walls and roofs. Consequently, the consumption trends generally follow those of the housing industry. Therefore, Government imposes tough quality control and quality assurance on the timber industry to grantee product standard meets the specifications in building industry.

Elastic modulus of trabecular bone material

Journal of Biomechanics, 1988
An ultrasonic technique was used to measure both the elastic modulus (Young's modulus) of trabecular bone material and the elastic modulus of the cancellous structure. The average trabecular modulus, measured on specimens obtained from three human and one bovine distal femora, was 13.0 GPa (S.D. 1.47) and 10.9 GPa (S.D. 1.57), respectively.

Anomalies of Elastic Modulus in Pb2Sr2YCu3O8+δ

physica status solidi (a), 1999
We have studied the structural instability of Pb 2 Sr 2 YCu 3 O 8+δ by means of low frequency elastic modulus measurements. A modulus anomaly was found near 190 °C in the δ=0 samples. After a small amount of extra oxygen was incorporated another modulus anomaly was observed near 30 °C.

Shrinkage stress is determined by the elastic modulus during shrinkage, not the final elastic modulus

Dental Materials
Polymerization shrinkage in restored teeth is implicated in restoration longevity. This study explored how development of shrinkage and elastic modulus of resin-based composites interact and discussed the level of residual stress they create.Residual stress was assessed by cuspal flexure of typodont premolars with 3 × 3 mm mesio-occlusal-distal ...
