jun 9, 2009 2. the interatomic bonds. so, what is the reason of change of elastic modulus with plastic deformation? any references??
the elastic modulus of the material affects how much it deflects under a load, after a material yields, it begins to experience a high rate of plastic deformation.
elastic behavior: when loads are small, how much deformation occurs? what materials deform least? plastic behavior: at what point does permanent.
tensile tests are used to determine the modulus of elasticity, elastic limit, the linear-elastic portion of the curve and it indi es that no plastic deformation has

experiences elastic deformation followed by plastic deformation. similarly, the bulk modulus or volumetric modulus of elasticity k, of a material is defined.
jun 5, 20 9 the ratio of stress to strain is the elastic modulus—stiffness, only the deformation: also known as plastic deformation, this is the warping that
may 8, 2020 the transition point between elastic and plastic deformation curve in the elastic zone; a higher modulus of elasticity indi es a stiffer material.
stress, strain, and elastic modulus, other elastic deformations, crystalline forces may cause permanent changes of shape or size, called plastic deformation.

when this happens, plastic deformation will occur. the elastic region of the stress versus strain has a slope equal to the modulus of elasticity, and the plastic
as such, the deformation of silly putty is significantly affected by strain rate. when silly putty is relative to one another, and we observe ductile fracture with great plastic deformation. when silly putty is modulus of elasticity. think about a
the elastic modulus measures the stiffness in a material, but strength is a function of and hardness are indi ors of a metal& 39;s resistance to plastic deformation.

cold extrusion involves the appli ion of high pressure—that is, a high bulk modulus—to a metal without heating it, and is used on materials such as tin, zinc, and
the deformation is said to be elastic if the material returns to its original size and is known as young& 39;s modulus, e, which is also known as the elastic modulus. once the plastic deformation region is reached, the stress-strain relationship
