Innovation application: Determination of Stress-Strain Characteristics in Bending

Title Determination of Stress-Strain Characteristics in Bending
Abstract

There is proposed determination of stress-strain parameters in bending (int. al. modulus of elasticity, stress and strain at maximum, stress and strain at break) for polymer materials and composites (int.al., nanocomposites) according to testing technology of the universal testing machine as well as appropriate international standards: LVS EN ISO 178 "Determination of flexural properties" and other.

Description of the technology

We offer determination of stress-strain parameters in bending (int. al. modulus of elasticity, stress and strain at maximum, stress and strain at break) of polymer materials (int.al., nanocomposites) at following conditions: load cells - 5 kN, 20 kN, 25 kN, 100kN; testing speed - from 0,001 to 500 mm/min.; testing temperatures - from -70°C to 300°C; cyclic loading option.
