Elastically stiff
WebElastic and Inelastic Collisions When objects collide, they can either stick together or bounce off one another, remaining separate. In this section, we’ll cover these two different types of collisions, first in one dimension and then in two dimensions. WebWhile they conduct heat and electricity like metals, they are elastically stiff, strong, brittle, and heat-tolerant like ceramics. They are resistant to chemical attack, readily machinable, and thermal shock, damage tolerant, and sometimes fatigue, creep, and oxidation resistant. MXene discovery

The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus. An elastic modulus has the form: = where stress is the force causing the deformation divided by the area to which the force is applied and strain is the ratio of the change in …
WebA high elastic modulus is typical for materials that are hard to deform; in other words, materials that require a high load to achieve a significant strain. An example is a steel … WebJan 1, 2011 · The model suggests that an elastically stiff interface greatly increases the stiffness of the polymer in response to an &lsquo instantaneous &rsquo step load, reduces the rapid creep response, and results in a rapid leveling off of the time-dependent strain curves. The response of the composite to increasing stiffness of the interface region ...
