Elastic modulus and application

A

An elastic modulus is a quantity that measures an object or substance’s resistance to being deformed elastically when a stress is applied to it.

Q

composite stiffness

longitudinal loading

A

To determine the longitudinal load–elongation curve of an artery, the hydrostatic pressure is held constant at a desired value, the length is increased in small steps, and the force recorded.

Q

composite stiffness

transverse loading

A

Transverse loading is a load applied vertically to the plane of the longitudinal axis of a configuration, such as a wind load. It causes the material to bend and rebound from its original position, with inner tensile and compressive straining associated with the change in curvature of the material.

Q

two types of composite production methods

A

pultrusion - is a manufacturing process for converting reinforced fibers and liquid resin into a fiber-reinforced plastic

filament winding - is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks).
