What is Failure Analysis and Investigation? Failure analysis is when an investigation takes place to determine the cause of failure, usually with the aim of taking corrective action to fix the problem and mitigate against further failures. Failure analysis is undertaken across all branches of manufacturing industry to prevent future asset and ...

We describe a complex failure mechanism in a 30-m high bench in a granodiorite quarry. This mechanism included a circular failure in completely decomposed granodiorite at the bottom of an unstable area pushing on a block of granodiorite. This first block induced subsidence and failure of a wedge of highly decomposed granodiorite, …

Two approaches to failure analysis are explained: analysis of individual failures and statistical analysis. Various criteria for failure sorting and classification are presented, as well as the main causes and mechanisms of failures. The text is accompanied by figures with characteristic fracture patterns. The chapter is …

Many bearings that fail are removed and replaced too quickly without sufficient levels of analysis into what caused their failure. This means that similar failures could occur again, resulting in further damage and costly unscheduled downtime.. Examination of the failure mode often reveals the true cause of bearing failure, but this …

Semiconductor Failure analysis (FA) is the process of determining how or why a semiconductor device has failed, often performed as a series of steps known as FA techniques . Device failure is defined as any non-conformance of the device to its electrical and/or visual/mechanical specifications. Failure analysis is necessary in order to ...

Secondly, a brief analysis of the cost of wind power projects based on equipment failure is presented. Thirdly, the current key technologies for intelligent operation and maintenance (O&M) in the …

Our model indicates relationships between multiple variables and their impacts on production in an operation. Data analysis was also applied to ground …

Bearing in mind the three-legged stool approach of device design/manufacturing, patient factors, and surgical technique, this article aims to inform the failure analyst of the metallurgical and materials engineering aspects of a medical device failure investigation. It focuses on the device "failures" that include fracture, wear, and corrosion.

This article discusses the failure analysis of several steel transmission pipeline failures, describes the causes and characteristics of specific pipeline failure modes, and introduces pipeline failure prevention and integrity management practices and methodologies. In addition, it covers the use of transmission pipeline in North America ...

The contribution investigates the use of root cause analysis (RCA) to identify the fundamental causes of failures or recurrent problems, which need to be corrected, …

The process of conventional risk analysis itself is generally comprised of four tasks: (1) systems and hazards identification, i.e. identifying the events that may have adverse effects on systems, (2) likelihood estimation, (3) consequence estimation, and (4) risk characterization [12].In this study, hazards identification focuses on identifiable …

To do so, a list of the hazards and their descriptions are first prepared. Then the hazard risk rating is conducted using the Failure Modes and Effects Analysis …

The analysis of failures of mining and heavy mechanical equipment, in general, follows the same guidelines and techniques as applied to other failures. Since these general …

In this research, the reliability analysis of loading equipment in Galcheshmeh travertine quarrying which consists of two loaders has been analyzed. In this study, two …

This article presents case histories that are intended as an overview of the unique types of failures encountered in the freight railroad industry. The discussion covers failures of axle journals, bearings, wheels, couplers, rails and rail welds, and track equipment.

It discusses the interaction of manufacturing-related cracking and service failures and primarily deals with failures that occur in service due to stresses caused by externally applied loads. The purpose of this article is to enable a failure analyst to identify the causative factors that lead to welded connection failure and to identify the ...

Block failure is a common type of uncertainty in blocky and layered rock slopes. One of the most critical types of block failure is a slide of slope top flexural toppling. In the current research, such kind of block failure is studied through numerical modeling. For this purpose, extensive field investigations and laboratory tests were conducted to …

Using our TSLOPE model we have been able to investigate, through back analysis, how GSI might vary at the bench failure. 2. UAV data capture. The UAV used to photograph the quarry was a DJI Phantom 4 UAV …

Abstract. We describe a complex failure mechanism in a 30-m high bench in a granodiorite quarry. This mechanism included a circular failure in completely decomposed granodiorite at the bottom of ...

Therefore, the fracture analysis should be done in the planning stage of a quarry before the quarrying starts, when it still is easy to place the faces in the proper directions. Also, the best direction of suggested faces for increasing the profitability of natural stone blocks is generally perpendicular to the dominant strike of discontinuities.

Large blackouts are typically caused by cascading failure propagating through a power system by means of a variety of processes. Because of the wide range of time scales, multiple interacting processes, and the huge number of possible interactions, the simulation and analysis of cascading blackouts is extremely complicated. This paper defines …

Failure analysis techniques vary widely based on the specific use cases. That being said, steps for conducting failure analysis follow the same pattern. Step #1: Define the problem. A well-defined problem statement is essential for any deep analysis. Failure analysis requires the engineers to define the problem as clearly and concisely …
