Failure modes

In this current study, the structural failure determination is carried out through a damage index based solely on the unhealthy state. A combination of the gapped smooth and modal curvature methods is the core of calculating the proposed indicator.

This paper presents a procedure to design cellular composite beams according to EN 1994-1-1. In addition, a parametric study is carried out to evaluate the influence of circular opening geometry to ultimate load and failure mode of a series of cellular composite beams. As a result, an optimal dimension of cellular beam is proposed.

The shear behavior of steel fiber reinforced concrete (SFRC) beams has been assessed in a large number of previous studies. However, the shear strength of corroded SFRC beams without shear reinforcement is still an unresolved topic. In this paper, the finite element models of non-corroded and corroded SFRC beams have been constructed and verified regarding load-displacement curves, crack patterns, and failure modes.

House of Risk Method is used to identify the most potential risk agents, while the fuzzy reasoning risk assessment model is used to determine the risk severity by risk agents. Based on the analysis, it is found that risk agent stock out of the product is the most potential risk agent in this industry. To reduce the impact, mitigation strategies are suggested for stock out product risk agents in warehouse are flexible supply base, safety stock, internal coordination, as well as create and control production schedules.

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 numerical wedge splitting tests show that in the case of brittle materials, the lower post-failure stress limit defined in the concrete damaged plasticity model resulted in energy consumption for crack propagation exceeding the defined fracture energy (114% higher in the case of a brittleness number of 4.4).

It is shown that the experimental failure loads are well predicted by means of both the UMTS-EMC and UMS-EMC criteria. Moreover, the experimental observations and the elastic-plastic finite element analyses indicate that the U-notched aluminum sheets fail by the large-scale yielding (LSY) regime.

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.

Redo Log History All transactions are recorded in the online redo log files. This allows for automatic recovery of transactions in the event of a database failure. If the database is configured for NOARCHIVELOG mode, no redo history is saved to archived log files, and recovery operations are limited and a loss of transaction work may occur. This is the result of the automatic recycling of log files, where older log files needed for recovery are overwritten and only the most recent part of the transaction history is available.
