A relation to describe rate-dependent material failure.

A New Approach for Stress State - Dependent Flow Localization Failure Bounded Through Ductile Damage in Dynamically Loaded Sheets

In this paper, a new approach is proposed for stress state - dependent flow localization in bifurcation failure model bounded through ductile damage in dynamically loaded sheets. Onset of localized necking is considered in phenomenological way for different strain rates to draw the forming limit diagram (FLD). Using a strain metal hardening exponent in the Vertex theory related to the strain ra...

An Attempt to Describe the Features of Patients with Chronic Renal Failure and the Factors Associated with this Disease Among Hemodialysis Patients in A Hospital in Tehran in 2016

Background and Objectives: Chronic renal failure (CRF) is an irreversible disorder of the renal function. The aim of this study was to  describe the features of patients with chronic renal failure and the factors associated with this disease among hemodialysis patients in a hospital in Tehrn in 2016.   Methods: In this cross-sectional descriptive study, patients presenting to the hemodialysis...

Almost Lack of Memory Property and its Relation with Periodic Failure Rate

This article has no abstract.

  Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them.   Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...

Managing Disasters Using Pressure Dependent Demand Analysis – Case Study of Shirpur Town

Water is the most essential component for sustaining lives of humans and other living creatures. Supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. But sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. Th...
