NDE 4.0 & Open-Source
3D Digital Twins
Unlocking Intelligent Data Management for NDT Laboratories — from reactive inspection to predictive, connected, cyber-physical infrastructure.

The Shift
From Reactive Inspection to Intelligent NDE
For decades, Non-Destructive Evaluation has been our silent guardian — detecting flaws, preventing failures. But the industry is now at an inflection point. Digital twins, IoT sensors, and open-source platforms are no longer experimental: they're production-ready.
This presentation — delivered at ICENDE 2025 — explores how testing and inspection labs can move from fragmented, paper-based workflows to a fully connected, cyber-human ecosystem. The opportunity is not theoretical. OMS has deployed this in practice across NDT companies in Australia, and the results are measurable.

NDE 4.0 Explained
A Paradigm Shift in Inspection Technology
NDE 4.0, derived from Industry 4.0, combines Cloud computing, IoT sensors, Big Data analytics, Machine Learning, and Digital Twins into a unified inspection intelligence layer. Think of it as a nervous system for infrastructure:
Sensors
The eyes and ears — continuous real-time condition data from physical assets
Cloud Computing
The brain — centralised processing, storage, and accessibility from anywhere
Digital Twins
The memory — living virtual replicas that update from sensor feeds
Machine Learning
The intuition — pattern recognition that flags anomalies before failures occur
Core Technology
Digital Twins in NDE
A digital twin is more than a 3D model — it's a living mirror of a physical asset. It watches sensor data, learns from historical patterns, and predicts where stress, fatigue, or cracks are likely to develop next. This shifts maintenance from scheduled guesswork to evidence-based prediction.
Real-time replicas for continuous condition monitoring
Simulate stress, fatigue, and crack propagation virtually
Link physical asset health to virtual simulation outcomes
Enable automated compliance documentation
Why Open-Source
Accessible, Scalable, and Cost-Effective
Proprietary NDT software often requires expensive licences, vendor lock-in, and limited customisation. Open-source 3D platforms like OpenModelica and Blender flip that model — giving labs full control, Python API integration, and native support for real-time IoT data streams.
Evident's open ecosystem embraces this philosophy, leveraging the .nde format built on HDF5 — universally readable by Python, MATLAB, and other tools, enabling frictionless data exchange across inspection systems.
Predictive Maintenance
Early Detection = Reduced Downtime
A crack begins forming in a bridge girder. Embedded sensors detect stress anomalies. The digital twin simulates crack propagation. Machine learning forecasts failure probability. Maintenance is triggered — before disaster strikes. This is the predictive power of NDE 4.0 in action.
