Coupled Thermoelasticity Impact Response Analysis of Composite Plates with SMA Wires in Thermal Environments

Impact responses of rectangular composite plates with embedded shape memory alloy (SMA) wires are investigated in the present research. The plate is assumed to be placed in a thermal environment; so that in contrast to the available researches in the field, the shape memory and ferroelasticity effects have to be considered also in addition to the superelasticity. The governing equations are der...

Security Analysis of VPN Configurations in Industrial Control Environments

Virtual private networks (VPNs) are widely recommended to protect otherwise insecure industrial control protocols. VPNs provide confidentiality, integrity and availability, and are often considered to be secure. However, implementation vulnerabilities and protocol flaws expose VPN weaknesses in many deployments. This paper uses a probabilistic model to evaluate and quantify the security of VPN ...

Analysis Methodology for Hydrogen Accident Scenarios in Complex Industrial Environments

This paper describes a general analysis methodology which was developed for consistent and mechanistic modeling of hydrogen behavior in complex industrial accident scenarios. The methodology includes four steps: 1. Three-dimensional CFD simulation of the time and space dependent hydrogen concentration in the computational domain. 2. Application of experiment-based criteria which allow to estima...

Anomaly Detection and Structural Analysis in Industrial Production Environments

Detecting anomalous behavior can be of critical importance in an industrial application context. While modern production sites feature sophisticated alarm management systems, they mostly react to single events. Due to the large number and various types of data sources a unified approach for anomaly detection is not always feasible. One prominent type of data are log entries of alarm messages. T...
