ATOA’s Virtual Testing Solutions Service
Virtual Test by Digital Engineering
Virtual Testing is transforming the way industries design, develop, and validate products. Traditionally, engineering relied on costly and time-consuming experimental tests, often constrained by materials, equipment, and safety limitations. While experiments remain essential, many properties and scenarios are either too expensive, too dangerous, or too complex to test physically.
ATOA’s Virtual Testing Services bridge this gap by replicating experiments in a CAE simulation environment, enabling faster, safer, and more cost-effective product development. Our multiphysics virtual testing platform allows clients to predict material, part, and system performance under real-world and extreme conditions—well before physical prototypes are built.
Physical experiments are indispensable, but they have critical limitations:
Material Cost Constraints – Some tests require large volumes of expensive materials.
Unrealistic Parameter Ranges – Certain extreme conditions (e.g., earthquakes, crashes) cannot be replicated safely in a lab.
Time-Intensive Processes – Iterative prototype testing extends development cycles.
Environment, Health & Safety Concerns – Hazardous testing can pose risks to personnel and infrastructure.
Virtual Testing overcomes these barriers, offering:
First-time-right design predictions.
“What-if” scenario exploration across multiple variables.
Safe replication of extreme environments.
Faster innovation cycles with fewer prototypes.
Importantly, Virtual Testing complements physical experiments—simulations guide focused, reduced testing, while experiments validate and verify.
Levels of Virtual Testing
ATOA offers Virtual Testing Services at four progressive levels, covering the entire material-to-system hierarchy:
Constituent Level
Virtual material characterization of base constituents such as fibers, powders, resins, or alloys.
Example: Predicting the elastic constants of polymer chains or creep performance of metals.
Coupon Level
Standardized material property prediction equivalent to laboratory coupon tests.
Example: Tensile modulus, fatigue strength, thermal conductivity, dielectric constants.
Part Level
Virtual testing of product parts under functional loads and environments.
Example: Fatigue testing of an automotive suspension arm or impact behavior of a helmet shell.
System Level
Full-scale virtual testing of integrated systems for real-world performance.
Example: Crash simulation of a vehicle, acoustic testing of a building panel, or seismic analysis of infrastructure.
This staged approach ensures traceability of properties from material constituents to complete systems, enabling confidence in performance across scales.

Advanced Virtual Testing Applications
Anisotropic Properties Prediction
Characterizing complex materials like composites, nano-materials, and metamaterials where traditional testing is costly or impractical.Extreme Condition Testing
Safe simulation of events such as earthquakes, hurricanes, crashes, or blasts, which are otherwise difficult to reproduce experimentally.Emergent Properties
Prediction of properties that arise from material interactions, such as multifunctional composites or smart materials.Reverse Engineering & Optimization
Using progressive damage modeling to understand material behavior and redesign for improved performance.
Standards and Compliance
Our simulations are performed in alignment with ASTM, ISO, and industry or National-specific standards, ensuring that results are directly relevant for:
Certification and regulatory submissions.
Product qualification and documentation.
Quality assurance and control.
By aligning with international standards, ATOA’s Virtual Testing results can substitute or reduce the need for repetitive experimental campaigns.
