[1] Earthquake ruptures are modeled as dynamically propagating shear cracks with the aim of gaining insight into the physical mechanisms governing their arrest or, otherwise, the often-observed variations in rupture speeds. Fault bends have been proposed as being the main cause for these variations. Following this line of reasoning, the existence of deviations from fault planarity is chosen as ...

Understanding the folding style of a fold-thrust belt is crucial to understand the nature and structural history of structures that may trap natural resources within the belt. In this research, the geometry and mechanism of a number of fault-related folds has been investigated based on field data and satellite image interpretations. The main study areas are: the Sohrevard and Ushtaniyan anticli...

This paper presents the method to solve the over loading problem and service restoration strategies for affected zones due to fault in a three feeder distribution network which deals with the estimation of load changes through feeder reconfiguration using the heuristic search technique. This method is based on minimum number of switching operations and minimum total IR losses. Software has been...

This article proposed a detection scheme for three-phase Line start permanent magnet synchronous motor (LSPMSM) under different levels of static eccentricity fault. Finite element method is used to simulate the healthy and faulty LSPMSM with percentages eccentricity. An accurate laboratory test experiment performed evaluate index. Effects loading condition on are also investigated. The fault re...

The constant requirement of aerospace industry to enhance the structural efficiency has driven usage high-performance composite materials, either monolithic or sandwich. However, structures are prone damage due high-velocity impact events such as bird strike, hail impact, etc. These can result in extensive including structure perforation, which will eventually degrade its post-impact residual s...

analysis and prediction of structural response to static or dynamic loading requires prediction of concrete response tovariable load histories. the constitutive equations for the mechanical behavior of concrete capable of seeing damage effects or crack growth procedure under loading/unloading/reloading was developed upon micro-plane framework. the proposed damage formulation has been built on t...

time-history analysis is defined as a kind of dynamic analysis increasingly used in design of structures and evaluation of existing ones. one of the important issues in the time-history analysis is selecting earthquake records. in this case, seismic design provisions states that time histories shall have similar source mechanisms, geological and seismological features with region under study. a...

[1] Several lines of evidence, including remote triggering of earthquakes and modulation of seismic tremor by Earth tides, suggest that faults weakenwhen subject to shaking and dynamic stresses associatedwith the passage of seismic waves. However, the origin of such dynamic weakening is poorly understood. Here we explore the role of acoustic resonance for dynamic fault weakening using laborator...

A conceptual model is proposed for the generation of low-angle normal faults in Metamorphic Core Complexes. The model is based on three assumptions: (1) the isostatic response to normal fault motion is of regional extent; (2) when a fault segment is significantly rotated from the optimum angle of slip, relative to the crustal stress field, it is replaced by a new planar fault oriented in the op...

A fault protection and location method for a dc bus micro grid system is presented in this paper. If a fault causes the dc bus to de-energize completely, it makes locating faults very difficult. The proposed algorithm can be implemented and executed by an intelligent electrical device for an individual node. The bus was segmented into overlapping nodes and links with circuit breakers (CBs) to i...
