Identifying Mechanical Characteristics of Materials with Non-lineai Behavior using Statistical Methods

摘要

Rubber and similar materials are often used as vibration insulators for technical systems. Their behavior is linear until a deformation of maximum 15% appears; crossing over this limit, the behavior becomes non-linear, meaning that the dynamic rigidity and implicitly the modulus of elasticity change its value as long as the element is stressed over this level under dynamic regime. The authors have developed one equipment and adequate methods to find out these parameters by statistical processing of data experimentally obtained with this equipment.
