Plastic Behavior

Plastic Behavior

A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and reloaded.

Members Made of Elastoplastic Material

The behavior of elastoplastic materials under bending stresses, particularly in structural members with rectangular cross-sections, is crucial for predicting material responses and understanding failure modes. Initially, when a bending moment is applied, the stress distribution across the section follows Hooke's Law and is linear and elastic. This distribution means the stress increases from the neutral axis to the maximum at the outer fibers, up to the elastic limit.
As the bending moment...

Summary

Soft denture liners with viscoelastic properties improve chewing function for edentulous patients. Materials with higher loss tangent (tan delta) and shear storage modulus (G') offered the best results.

Background:

Soft denture liners cushion forces for edentulous patients.
Viscoelastic properties are hypothesized to enhance masticatory function.

Purpose of the Study:

To evaluate the effect of viscoelastic properties of soft denture liners on masticatory function.
To compare the performance of different soft liner materials.

Main Methods:

Determined viscoelastic properties (G', G'', tan delta) of 6 materials using a dynamic viscoelastometer.
Assessed masticatory function in 10 subjects via bite force, chewing time/frequency, and visual analogue scales.

Main Results:

Acrylic materials showed viscoelastic behavior; silicones exhibited elastic behavior.
Masticatory function improvement order: acrylic permanent > silicone > acrylic temporary.
Higher tan delta and G' correlated with better masticatory function.

Conclusions:

Viscoelastic soft denture liners, particularly acrylic permanent materials, optimize masticatory function.
Material properties like tan delta and G' are key indicators for effective soft liners.
