Failure modes

The focus of this paper is on studying power control for Interlinking Converters (ICs) to maintain stable voltage frequency on both AC and DC sides for a hybrid AC/DC microgrid in standalone mode, as well as the balance of active and reactive power. The control method also enhancing the resilience of the hybrid AC/DC microgrid during sudden load increases or power source failures in the AC and DC subgrids.

In this study, a comprehensive database of 146 URM walls was compiled from 26 research groups and employed to evaluate the accuracy of established guidelines, including ASCE 41-17, NZSEE, Eurocode 6, and GB50003. The comparative analysis showed that ASCE 41-17 provided the most accurate predictions with acceptable safety levels, while NZSEE produced more conservative estimates and excelled in predicting diagonal shear failure modes.

This paper investigates flexural behavior and analytical approach for predicting the load and deflection at critical performance points of reinforced concrete (RC) beams strengthened with prestressed carbon fiber-reinforced polymer (CFRP) sheets. A finite element model is developed to simulate the interaction between the RC beam and the CFRP sheets, capturing key aspects such as failure modes, ultimate load, and mechanical behavior across the three phases of failure.

This study focuses on experimental testing and subsequent numerical analysis of impacted and pre-loaded composite coupons and bonded composite scarf joints under varying impact conditions. A methodology will be developed for the numerical modelling of preloaded impact tests to enable capture of critical failure modes and ultimate failure. The main aim is to validate a modelling strategy that will provide accurate failure characterisation of the tested joints using numerical analysis.

The present work summarizes some recent experimental, theoretical and numerical results on brittle fracture of isostatic polycrystalline graphite. The analyses have been carried out on V-notched samples under mixed mode (I+II), torsion and compression loading, considering various combinations of the notch tip radius, opening angle and notch tilt angle.

The curves were developed in a computational manner in terms of the notch stress intensity factors and based on the suitable failure concept of the maximum tangential stress (MTS) utilized frequently in the past by the author and his co-researchers for predicting mixed mode brittle fracture in extensive notched specimens.
