Plastics molding simulation data
Simulations of manufacturing processes such as injection molding, blow molding,
and thermoforming require highly complex, non-linear data inputs, including
viscosity, thermal properties, PVT, viscoelastic, and mechanical properties. We
generate data and analysis-ready material files for all major simulation programs
used in the industry today.
Crash and drop test simulation data
Simulation of crash and impact phenomena require rate-dependent properties. These
are usually stress-strain curves measured over several decades of strain rate. We
provide rate-dependent data and parameter conversion for metals, plastics, rubbers
and foams, and composites, including more complex experiments to model yield
surfaces, advanced plasticity and failure.
Hyperelastic modeling of rubber
A hyperelastic material can be thought of as any type of rubbery material that exhibits
large recoverable strains up to failure. Because such material is highly deformable and
the Poisson’s ratio is nearly 0.5, deforming the material by stretching, compressing,
or twisting in one direction results in a large deformation response in other directions.
This coupling means that the material behavior cannot be predicted using properties
generated in only one mode of deformation. We support all commonly used finiteelement
simulations with multi-mode test data, along with fitting to mathematical
models such as the Mooney-Rivlin or Ogden equations.
Testing of foams
Foams are complex materials, the behavior of which can be tailored for the application
purpose. The most common mode of deformation is by compression. Foams usually
are not strong in tension or shear and are rarely intentionally subjected to deformation
in these modes. Our support for foam modeling includes testing for factors such as rate
dependency, hyperbolic extrapolation for impact simulation, and hyper-viscoelasticity.
Creep, Fatigue, and long term behavior
The modeling of time-based phenomena is gaining widespread use in industry as
analysts try to predict the long term behavior of products. While classical creep
experiments remain the mainstay for this kind of analysis, viscoelastic modeling
provides predictive advantages at small strains for certain types of materials. Creep
rupture experiments are useful to gauge time-dependent failure while cyclic fatigue
data are vital to ensure that products do not fail in the field.
