Macrophages bend long fibres with flexural rigidity lower than 3 mN·nm2 to avoid frustrated phagocytosis [PDF]
Particle and Fibre ToxicologyBackground It is an established toxicological principle that the inhalation pathogenicity of respirable and biodurable fibres is caused by excessive fibre length as alveolar macrophages fail to uptake and remove such fibres.

Flexural rigidity of hawkmoth antennae depends on the bending direction. [PDF]
Acta BiomaterTo probe its environment, the flying insect controllably flexes, twists, and maneuvers its antennae by coupling mechanical deformations with the sensory output. We question how the materials properties of insect antennae could influence their performance.

Modeling the flexural rigidity of rod photoreceptors. [PDF]
Biophys J, 2013 In vertebrate eyes, the rod photoreceptor has a modified cilium with an extended cylindrical structure specialized for phototransduction called the outer segment (OS). The OS has numerous stacked membrane disks and can bend or break when subjected to mechanical forces.

Measuring Flexural Rigidity of Fabrics
Journal of the Textile Machinery Society of Japan, 1967 A new method to measure the flexural rigidity of fabrics is discussed here. It treats a fabric as an elastica. The two ends of a specimen, 2L long, are clamped vertically 2X apart. The edge of a knife compresses the center of the specimen placed on the cross head of an Instron-type tensile tester.

Magnetic torque-based method for quantifying the flexural rigidity of microfibers
Journal of Science: Advanced Materials and DevicesProbing the flexural rigidity of micropillars and microfibers is challenging as they are short and difficult to handle. We developed a magnetic torque methodology where a coil-generated uniform magnetic field acts on a magnetic microrod attached to the ...
