Study on Hot Deformation Behavior of High Strength Construction Steel 34CrNiMo6

MATEC Web of Conferences, 2018
The hot pressure deformation tests were carried out by using Gleeble-2000 simulator at the temperature of 950°C ~ 1150 °C and strain rate of 0.001s-1 ~ 1s-1 for a kind of high strength construction steel 34CrNiMo6 for Crankshafts and the curve of its ...

Vestibular Patient Journey: Insights From Vestibular Disorders Association (VeDA) Registry

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Vestibular symptoms impose a high burden of disability. Understanding real‐world diagnostic and treatment pathways can identify care gaps and guide interventions. We aimed to characterize symptom profiles, diagnostic trends, provider involvement, and treatment patterns in vestibular disorders.

Description of stress–strain curves for stainless steel alloys

Materials & Design, 2015
There is a wide variety of stainless steel alloys, but all are characterized by a rounded stress-strain response with no sharply defined yield point. This behaviour can be represented analytically by different material models, the most popular of which are based on the Ramberg-Osgood formulations or extensions thereof.

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

High temperature constitutive model of q345B steel

Metalurgija, 2022
In order to accurately predict the flow stress of Q345B steel at high temperature, the Q345B steel was subjected to a hot compression test on the Gleeble-1500D thermal simulation test machine at a deformation temperature of 1 173,15~1 373,15 K and a ...

Theoretical study on loading history dependence of dynamic failure strength for brittle materials

Scientific Reports
Whether the dynamic failure strength of brittle materials is an intrinsic material property has been debated, owing to its dependence on loading history. To further study such a dependence, a characteristic time failure criterion for brittle materials is

Stress Strain Curves

AbstractTraditionally, stress strain curves for example from tensile testing are described with empirical models with a number of adjustable parameters such as Hollomon, Ludwik, Voce and Swift. With such models it is difficult or impossible to generalize and extrapolate.
