Elastomeric (rubber) materials play a critical role in many industries—automotive, defense, rail systems, industrial machinery, and medical applications—by providing vibration isolation, sealing, and impact damping. Throughout their service life, these components are exposed to varying load levels, cyclic loading with different amplitudes, and environmental effects.
For this reason, accurately predicting the lifetime of elastomer components is essential for product safety, reliability, and cost optimization.
This is exactly where Endurica DT (Damage Tracking) becomes a game-changing solution.
Endurica DT is an advanced engineering software for time-based, incremental fatigue analysis of elastomer components.
While Endurica CL calculates how many repeats a single load history can withstand (repeats-to-failure), Endurica DT evaluates the combined effects of multiple load cases across the entire service life of the component.
In simple terms:
CL: “How many repeats will this load cycle survive?”
DT: “How will this component accumulate damage under real operating conditions, and when will it reach end of life?”
This ability makes Endurica DT uniquely suited for modeling real-world, variable-amplitude loading scenarios.
Standard single-cycle fatigue predictions often fail to fully represent the complexity of real operating conditions.
Endurica DT handles:
Variable load levels
Multi-step test sequences (e.g., FMVSS procedures)
Block cycle programs
Histogram-based load profiles
and tracks damage accumulation incrementally.
Endurica DT monitors critical parameters throughout the product’s operational life:
Crack size growth
Damage accumulation rate
Stiffness loss
Strain energy density evolution
Equivalent ageing time
This enables engineers to understand how the material truly ages in the field.
The software determines the remaining useful life (RUL) based on your defined end-of-life criteria, such as:
a specific crack length, or
a defined percentage of stiffness reduction.
This provides exceptional value for warranty planning and durability management.
Endurica DT works seamlessly with leading FEA platforms such as Ansys, Abaqus, and MSC Marc.
As stiffness degrades over time, the FEA model is automatically updated:
stress distributions change,
strain energy values shift,
crack growth behavior evolves.
This enables truly realistic, physics-based fatigue simulations.
Below is the workflow used in typical elastomer fatigue projects completed by Fetech Advanced Engineering:
Endurica requires specialized elastomer fatigue testing to generate a complete material database:
Crack growth tests
Fatigue-to-failure tests
Mullins effect & relaxation behavior
Temperature-dependent properties
Ageing behavior
Hyperelastic model parameters
These tests generate the Endurica Material File, which fully characterizes rubber fatigue behavior.
The engineering team prepares:
Proper meshing
Hyperelastic material model (Ogden, Yeoh, Arruda-Boyce, etc.)
Load boundary conditions
Strain/energy distributions across the geometry
The FEA output feeds Endurica with the required “strain history” data.
A realistic duty cycle is constructed based on the real operating profile:
Low-load / high-load block cycles
FMVSS-type test sequences
Road load histogram data
Strain or acceleration time histories
Complex signals can be optimized using Endurica EIE.
For each load step, Endurica DT incrementally updates:
crack length
damage level
stiffness loss
maximum strain energy density
equivalent ageing time
At specified checkpoints, FEA simulations are repeated with:
updated stiffness,
aged material behavior,
evolved crack growth state.
Endurica DT generates comprehensive outputs:
remaining life at critical points
time-dependent damage growth
stiffness degradation curves
sensitivity to duty-cycle variations
design improvement suggestions
