A deformation mechanism map is a way of representing the dominant deformation mechanism in a material loaded under a given set of conditions and thereby its likely failure mode. Deformation mechanism maps consist of some kind of stress plotted against some kind of temperature axis, typically stress normalised using the shear modulus versus homologous temperature. For a given set of operating conditions calculations are undergone and experiments performed to determine the predominant mechanism operative for a given material.

Famous quotes containing the words mechanism and/or map:
“I’ve never known a Philadelphian who wasn’t a downright “character;” possibly a defense mechanism resulting from the dullness of their native habitat.”
—Anita Loos (1888–1981)
“When I had mapped the pond ... I laid a rule on the map lengthwise, and then breadthwise, and found, to my surprise, that the line of greatest length intersected the line of greatest breadth exactly at the point of greatest depth.”
—Henry David Thoreau (1817–1862)
