A novel energy sink with piecewise linear stiffness

Stiffness is the extent to which an object resists deformation in response to an applied force. The complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is. Se mer The stiffness, $${\displaystyle k,}$$ of a body is a measure of the resistance offered by an elastic body to deformation. For an elastic body with a single degree of freedom (DOF) (for example, stretching or compression of a … Se mer The inverse of stiffness is flexibility or compliance, typically measured in units of metres per newton. In rheology, it may be defined as the ratio of … Se mer • Bending stiffness • Compliant mechanism – Mechanism which transmits force through elastic body deformation • Elasticity (physics) – Physical property when materials or objects … Se mer The stiffness of a structure is of principal importance in many engineering applications, so the modulus of elasticity is often one of the primary properties considered when … Se mer NettetStiffness The options are: Spring Linear A single stiffness value is entered, which acts in both the positive and negative directions.

Stiffness occurs when stability requirements, rather than those of accuracy, constrain the step length. Stiffness occurs when some components of the solution decay much more rapidly than others.
