Polymer Analysis

Veryst provides expert services for product design, manufacturing processes, and failure analysis of polymeric parts and components. Our expertise includes experimental characterization, computer modeling, and engineering failure analysis. Much of our work is based on advanced characterization and physically-based computer models to solve industrial problems involving polymer systems.

The mechanical response of polymeric materials (rubbers, elastomers, thermoplastics, thermosets, and biomaterials) are characterized by significant nonlinear effects, including:

  • Creep
  • Large deformations
  • Temperature-dependence
  • Anisotropy
  • Texture development
  • Yielding
  • Stress relaxation
  • Crazing
  • Fracture and failure
  • Aging
  • Coupled effects
  • Composites

Many of these effects are often active in the intended service environment of a polymer product, and it is important to understand their influence on product performance and lifetime.

Services include:

  • Analysis of material compositions and structures
  • Experimental testing of the mechanical response under different conditions, including time effects, rate effects, temperature effects, and environmental effects
  • Modeling and predictions of mechanical behavior, including creep, stress relaxation, yielding, crazing, texture development, anisotropic behavior, temperature dependence, and physical and chemical aging
  • Fatigue and fracture mechanics analysis
  • Finite element simulations and predictions of large deformations and complex geometries
  • Analysis of coupled effects

User Material Subroutines for Finite Element Programs

Veryst also provides advanced finite element user-material subroutines for simulation of complex polymer materials, including:

  • Foams
  • Fluoropolymers
  • Hydrogels
  • Polycarbonate Urethane (PCU)
  • Elastomers
  • Thermoplastics
  • Thermoplastic Urethane (TPU)
