ATOA’s Life Design Solutions Services
Life Design by Digital Engineering
All products have a finite life. Over time, materials degrade, structures accumulate damage, and performance deteriorates under environmental, mechanical, or operational stresses. Designing only for initial performance is no longer sufficient—designing for life is critical to ensuring safety, reliability, and cost-effectiveness across a product’s service duration.
At ATOA, we offer Life Design Solutions and Life Prediction Services that integrate simulation, experimental data, and practical engineering experience to predict how products behave over time. By accounting for fatigue, creep, stress relaxation, corrosion, and extreme events, we help industries ensure their products not only perform on day one, but continue to do so throughout their intended lifespan.
Products today operate in increasingly demanding environments—aircraft wings under cyclic stresses, offshore structures exposed to waves, biomedical implants subjected to body fluids, or electronics under thermal cycling. The cost of failure can be catastrophic: financial loss, safety risks, and environmental hazards.
Life design and prediction provide critical benefits:
Reliability assurance: Preventing premature failures.
Safety compliance: Meeting stringent regulatory standards.
Cost savings: Reducing downtime, maintenance, and warranty claims.
Sustainability: Extending product lifecycles and reducing waste.
By combining physics-based simulation with time-dependent modeling, ATOA ensures that products are designed for durability, resilience, and longevity.
ATOA’s Life Prediction Framework
Fatigue Life Prediction
Fatigue is one of the most common causes of failure, especially in structures subjected to cyclic loading. We provide:
High-cycle fatigue prediction for aerospace, automotive, and rotating machinery.
Low-cycle fatigue analysis for power systems and heavy-duty components.
Multiaxial fatigue modeling for complex load paths.
SN curve-based analysis, predicting the relationship between stress amplitude and number of cycles to failure.
Application Example: Designing wind turbine blades or aircraft wing that survive millions of stress cycles over decades.
Damage Growth Prediction
Cracks and defects often initiate at microscopic levels and propagate over time. We model:
Fracture mechanics and crack propagation.
Damage mechanics at the material level.
Residual strength prediction of damaged components.
This enables early detection and repair planning, preventing catastrophic failures.
Example: Predicting crack growth in aircraft fuselages under pressurization cycles.
Creep Behaviour Prediction
At elevated temperatures and stresses, materials undergo time-dependent deformation known as creep. We simulate:
Primary, secondary, and tertiary creep regimes.
Creep rupture prediction under long-term loads.
Creep–fatigue interaction in high-temperature applications.
Example: Life prediction for turbine blades in power plants or jet engines.
Stress Relaxation Prediction
In some applications, stresses reduce over time under constant strain, affecting product functionality. We provide simulations for:
Stress relaxation in polymers, composites, and elastomers.
Residual stress relaxation in welded and additive manufactured parts.
Example: Predicting long-term performance of bolted joints in composite aerospace structures.
Dynamic & Strain-Rate Dependent Loading
The rate at which loads are applied can significantly affect performance. ATOA specializes in:
Impact simulations for automotive crashworthiness and packaging.
Seismic simulations for building and infrastructure resilience.
Blast and shock simulations for defense applications.
Example: Predicting the survivability of offshore structures under extreme wave loading.
Extreme Load Cases
Products must be designed for unexpected or extreme events to ensure safety and reliability. We simulate:
Storm and hurricane loading on buildings, towers, and wind turbines.
Earthquake resilience of structures and industrial equipment.
Hydrodynamic loading of marine vessels and offshore platforms.
This ensures that products are designed not just for average conditions, but for worst-case scenarios.
Multiphysics Life Prediction
Real-world degradation is often driven by combined effects, not just single mechanisms. ATOA’s multiphysics expertise enables us to simulate:
Stress-assisted corrosion: Metal weakening under combined stress and corrosive environments.
Radiation damage + fatigue: For nuclear and aerospace applications.
Thermo-mechanical fatigue: Caused by repeated heating/cooling cycles in electronics and power systems.
By coupling physics domains, we provide accurate, holistic life predictions.
Industrial Applications
Our life prediction services apply across industries:
Aerospace & Defense: Fatigue life of airframes, crack growth in fuselages, vibration life of avionics.
Automotive & Transportation: Crash and fatigue simulations for chassis, dynamic impact life prediction.
Energy & Power: Creep life of turbines, fatigue of offshore wind turbines, corrosion-assisted degradation of pipelines.
Biomedical Devices: Fatigue life of implants, stress relaxation in polymer-based prosthetics.
Civil & Infrastructure: Seismic and storm resilience of buildings, fatigue life of bridges.
Electronics & Semiconductors: Thermo-mechanical fatigue of solder joints, residual performance under cyclic loading.
Methodologies and Tools
ATOA employs a combination of:
Physics-based simulation for stress, fatigue, creep, and dynamics.
