Mechanical Properties of Glass

2019
This chapter focuses on the mechanical properties and behavior of glasses below their glass transition temperature. In this temperature range, they are usually seen as perfectly brittle materials: materials that deform only elastically, until they break. This chapter explores the behavior of glasses from the domain from elasticity to fracture. We first

Mechanical Properties of Viruses

2013
Structural biology techniques have greatly contributed to unveil the relationships between structure, properties and functions of viruses. In recent years, classic structural approaches are being complemented by single-molecule techniques such as atomic force microscopy and optical tweezers to study physical properties and functions of viral particles ...

Mechanical properties of arteries

Biorheology, 1982
For the description of the mechanical properties of the arterial wall, a number of different models and mathematical approaches of varying complexity have been used. Most investigations based on the elastomeric approach have been related to the elastic properties of arteries, while relatively little is known about the arterial wall viscosity (eta w ...

Mechanical Properties of Nanostructures

2004
Structural integrity is of paramount importance in all devices. Load applied during the use of devices can result in component failure. Cracks can develop and propagate under tensile stresses, leading to failure. Knowledge of the mechanical properties of nanostructures is necessary for designing realistic MEMS/NEMS and BioMEMS/BioNEMS devices.

Mechanical Properties of Viruses

2010
If a virus releases its genomic content prematurely, it loses its infective capability. Yet, the viral shell does need to open at a specific place and time to ensure genome delivery into a new host. Hence, the chemical and mechanical properties of capsids are carefully tuned to fulfill these constraints.

Mechanical properties of the lung

British Journal of Diseases of the Chest, 1960
Summary (1) The pressures developed at the mouth at different chest volumes, when relaxing against an obstruction, characterise the elastic properties of the lung and chest wall. During movement additional pressures are necessary to overcome frictional forces due to the frictional resistance of the lungs and chest wall and the resistance to ...

Mechanical Testing and Properties

1991
We select a material by matching its mechanical properties to the service conditions required of the component. The first step in the selection process requires that we analyse the application to determine the most important characteristics that the material must possess. Should it be strong, or stiff, or ductile?

Mechanical Properties of Muscles

1987
Skeletal muscle is made up of long fibres, terminated at each end by tendinous material attached to the bone. These fibres are formed from a syncitium of cells whose walls fuse during development, and hence have many nuclei spread throughout their length.

Mechanical Properties

2013
In recent years, the understanding of the basic physical relationships between the nanoscale structure and the macroscale properties of PNCs has received considerable attention. The designing of nanocomposites with only the desired properties requires precise control of the dispersed structure of the silicate platelets in the polymer matrix ...
