Method to determine the strain-rate sensitivity of a superplastic material from the initial slopes of its stress–strain curves New method to estimate quantitatively the strain-rate sensitivity of a superplastic material is suggested. It is based upon measurements of the initial slo... RA Vasin,FU...
In this paper, we used high-speed-friction tests on limestone and shale of the Qixia Formation to determine strain- and strain-rate- weakening of the rupture surface of the Jiweishan rock avalanche. The strain- and strain-rate- weakening model inferred that the friction coefficient of the ...
How to determine it? Usually, Material constant "A" and "m" are used for creep. 3 RepliesLast Post 2014年3月20日 GMT+8 18:09 Henrik SönnerlindCOMSOL Employee Posted:1 decade ago Hi, As you say, Norton's law is commonly expresses the strain rate ...
At this point in the measurement system, waveform data from the modules is used to calculate any power quality parameter desired. Some of these calculations are fairly simple while others are complex calculations aggregated over several cycles, seconds, or minutes to determine the ultimate quality. ...
To take steps to reduce work-related stress, here are a few options: Take up a leisure hobby you enjoy after work. This can help to direct thoughts away from job-related worries and improve cognitive detachment. Leisure activities are anything you enjoy that occupies your attention, such as ...
At high plastic strain rates dislocations may be required to move so quickly that dislocation damping forces determine the flow stress. In this note an estimate is made of strain rate at which dislocation damping becomes important. In the plastic flow stress range of 10 MPa to 100 MPa (for ...

Going to an in-state public college is one of the best ways to graduate without debt. Of the students who graduate with no debt, almost all of them are going to colleges that cost less than $8,000 a year, and those are mostly two-year colleges. That's fine if you're tr...
Consult an insurance advisor to determine how to calculate potential cash value accumulation of your specific permanent life insurance policy. Different Policies Accumulate Cash Value in Different Ways Cash value accumulation isn't uniform. It varies depending on the type of policy you have.2 ...
Companies and analysts use many measurements to determine a company's profitability. ROE shows performance based on shareholder equity. ROA shows company profitability based on its total assets. Thereturn on debt (ROD)measures how much a company profits from borrowed or leveraged funds. The big fac...
