Single-Point and Surface Quality Assessment Algorithm in Continuous Production with the Use of 3D Laser Doppler Scanning Vibrometry System

Lukasz Scislo

Summary: In the current economic situation, companies need to reduce production time without compromising on product quality. This article proposes the use of modern solutions like optical measurement systems to perform quality control without additional stoppage time. By using the Laser Doppler Vibrometer, the measurement process can be completed quickly for each product. The article also introduces a quality assurance algorithm that compares each product's modal responses to an ideal template and stores this information in the cloud, making it suitable for a factory quality management system based on the Industry 4.0 concept.

Modeling of a realistic barely visible impact damage in composite structures based on NDT techniques and numerical simulations

Andrzej Katunin et al.

Summary: The authors presented a method in this paper to parametrically model the barely visible impact damage (BVID) in carbon fiber-reinforced composite structures based on X-ray computed tomography scans, ultrasonic B- and C-Scans, and numerical simulations. The resulting generic models of BVID were validated on X-ray computed tomography scans, providing a successful reconstruction and validation method for such damages.
