Visca™ NLVE add-on module for Abaqus is an advanced nonlinear viscoelastic material definition for plastic & rubber simulation. The theoretical basis builds on decades of development in the technical literature. Akin to time-temperature superposition (TTS), this reduced time approach is essentially time-entropy superposition (TSS).
At its core, the reduced time approach requires high quality experimental data. Psylotech provides contract testing services, leveraging proprietary instrumentation. We produce time and temperature dependent bulk and shear modulus and ultimately, the complete viscoelastic stiffness tensor.
The SOFTWARE and the DATA form two prongs of a complete solution. Companies are empowered to quickly and cost effectively implement effective nonlinear polymer simulation, accommodating time, rate, temperature, pressure and large strain effects on plastics and rubbers.
