Document Summary
Stress strain and the science of elasticity how materials behave: The science of elasticity is about the interactions between forces and deflections in materials and structures. gordon. Every material sits somewhere on a scale between stiffness and compliance, a scale of elasticity. The concept of the elastic conditions at a specified point inside a material is the concept of stress and strain. Numerically, the stress in any direction at a given point in a material is simply the force or load which happens to be acting in that direction at the point. (gordon chapt. When stressed, all materials deform: the bonds between molecules & atoms are pulled apart or pushed together a piece of material gets a little longer or a little shorter: this is. Strain definition: increase of length divided by original length. At moderate force magnitudes strain follows hooke"s law, is hookean".
