Aims

Mechanical Systems Reliability and Diagnostics (MSRD) is an international, peer-reviewed, open-access journal devoted to the study of reliability, degradation, monitoring, and diagnostic processes in mechanical systems operating under practical and industrial conditions. The journal publishes research that examines how mechanical systems evolve in service, how failure mechanisms develop and interact, and how system health can be assessed, interpreted, and managed through analytical, experimental, and data-informed approaches.

The journal considers mechanical systems as operational entities whose behaviour changes over time under load, wear, environmental exposure, and varying usage conditions. Emphasis is placed on system-level analysis of degradation behaviour, failure propagation, diagnostic interpretation, and maintenance decision processes across the life cycle of engineered systems.

Particular attention is given to the analytical foundations of reliability and diagnostics. This includes modelling of degradation and failure processes, structured interpretation of monitoring signals, integration of measurements with physical system understanding, and formulation of maintenance and life-cycle decisions grounded in observable system evidence. Submissions are expected to establish a clear link between mechanical behaviour, measurable indicators, and reliability inference, rather than presenting algorithmic refinements or descriptive case material without analytical depth.

The journal supports research that improves understanding of how mechanical systems can be monitored and managed to sustain dependable operation under uncertainty. Studies combining experimental validation, transparent modelling assumptions, and reproducible diagnostic reasoning are especially encouraged. Clarity of system definition, traceability of inference, and robustness of conclusions are central evaluation criteria.

MSRD welcomes conceptual, methodological, computational, and experimentally grounded contributions that advance systematic understanding of failure, health, and operational integrity in mechanical systems. The journal is published quarterly by Acadlore and follows a structured peer-review process designed to ensure methodological transparency, consistency of evaluation, and analytical rigour.

Key features of MSRD include:

Focuses on mechanical systems as evolving operational systems rather than isolated components or purely theoretical abstractions;
Emphasises reliability, degradation behaviour, and diagnostic reasoning supported by measurable system response and engineering evidence;
Requires explicit analytical, experimental, or modelling frameworks linking system behaviour to reliability assessment or diagnostic interpretation;
Encourages work on fault detection, degradation modelling, and life prediction within a clearly defined system context;
Values integration of monitoring data with physical modelling, statistical reasoning, or structured diagnostic logic;
Supports comparative and validation-oriented studies where methods are assessed against experimental or field evidence;
Maintains editorial standards prioritising transparency of assumptions, reproducibility of analysis, and coherence between observations and conclusions.
