Dynamic Damage Testing
To characterize dynamic damage and fracture properties of materials, at DyMaLab multiple sample geometries and loading configurations have been developed. Aiming at high stress triaxialities, notched samples loaded at high strain rate in the split Hopkinson tensile bar are used. For negative stress triaxialities, dynamic compression of constrained samples or combined torsion/compression are performed. Low […]
Dynamic Torsion Testing
For dynamic torsion testing, DyMaLab disposes of a Split Hopkinson Torsion Bar setup with a large deformation capacity. The setup is used to characterize the shear response of a wide range of materials at strain rates from 100 s-1 up to 10 000 s-1. For torsion tests, thin-walled tube samples are used sandwiched between two long […]
Dynamic Shear Testing
At DyMaLab a novel shear specimen geometry was developed that can be used for static and dynamic tests. The main objectives during the design of the shear specimen were to obtain a homogeneous stress state with low stress triaxiality in the zone of the specimen subjected to shear and to be suited for dynamic testing. […]
Dynamic Compression Testing
For dynamic compression testing, DyMaLab disposes of a Split Hopkinson Compression Bar (SHCB) setup with a large deformation capacity. SHCB setups are used to study the constitutive, damage and fracture behaviour of materials at strain rates from 100 s-1 up to 10 000 s-1. As is the case for tensile setups, SHCB setups involve a short […]
Dynamic Tensile Testing
For dynamic tensile testing, DyMaLab disposes of a Split Hopkinson Tensile Bar (SHTB) setup with a large deformation capacity. SHTB setups are used to study the constitutive, damage and fracture behaviour of materials at strain rates from 100 s-1 up to 10 000 s-1. The concept of the Split Hopkinson Tensile Bar setup involves a short […]
