Definition: The word "aeroelastic" comes from a Greek word that means "airy elastic." In the Bible, this term appears in several passages where it refers to the properties or qualities of a material that are favorable to its ability to absorb shock waves, which is similar to air resistance. Hereβs an example: In the book of Ezekiel, the prophet Jeremiah speaks of a type of air (airy elastic) that he encounters during his journey through the valley of the shadow of the two waters. This verse translates as "He saw a great cloud; and it overflowed with the breath of the earth, like the air of the earth." Here, the word "aeroelastic" is used figuratively to describe this type of material. In essence, the word 'aeroelastic' signifies that the material exhibits characteristics conducive to resisting or absorbing shock waves during its journey through a medium.
