CARES SOFTWARE - Features
CARES ADVANCED FEATURES
- CARES/ANSYS/PDS - Probabilistic Component Life Prediction - Allows the effects of component stochastic variables to be considered in life prediction.
- CARES/WeibPar - For non-standard specimen geometries where closed form solutions do not exist, WeibPar utilizes CARES to calculate the effective volume/area from a finite element model of the specimen.
Combined with the failure data parameter estimation, the effective volume/area is subsequently used by WeibPar in calculation of the Weibull material scale parameter.
- CARES/WeibPar - WeibPar additionally utilizes CARES in the calculation of confidence bounds on the component reliability via Monte Carlo bootstrap techniques.
CARES STANDARD FEATURES
- Brittle Material Reliability Analysis
- Time Independent (Fast Fracture)
- Time Dependent (Slow Crack Growth)
- Creep (Static Fatigue)
- Monotonically Increasing (Dynamic Fatigue)
- Transient - Time Dependent Reliability (probability of survival) of components subjected to transient (multiple load step) thermomechanical loading
- Finite Element Analysis - Interaction with the FEA Results files includes extraction of Geometry, Temperature and Stress results for the following:
- Volume elements
- Surface elements
- Axisymmetric elements
- Multiple load steps
- Psuedo-surface - the free face of Volume elements may be identified and treated as a surface in CARES
