Mortar Properties

Mortar Properties

Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...

Members Made of Elastoplastic Material

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...

Area of Science:

Sports Medicine
Materials Science
Biomaterials Engineering

Background:

Growing concern for preventing sports-related dental injuries.
Need for improved protective equipment, specifically mouthguards.
Importance of material properties and visibility in mouthguard effectiveness.

Purpose of the Study:

To evaluate the physical properties (hardness, tear strength, tear energy) of custom mouthguard materials.
To assess the visibility of different colored mouthguards.
To provide data for improving mouthguard design and regulation enforcement.

Main Methods:

Machine testing of hardness, tear strength, and tear energy on nine custom mouthguard materials.
Evaluation of material debonding during tear energy tests.
Human subject and observer testing for mouthguard visibility.

Main Results:

Four materials (polyvinyl acetate-polyethylene, hard polyurethane) exhibited high hardness, tear strength, and tear energy.
Two materials failed due to debonding during tear energy testing.
Yellow mouthguards demonstrated nearly double the visibility distance compared to clear ones.

Conclusions:

Certain custom mouthguard materials offer superior mechanical properties for enhanced protection.
Material selection is critical, as some materials may fail under stress.
Color, particularly yellow, significantly impacts mouthguard visibility, potentially improving safety and compliance.
