How can the effect of the magnetic field of a solenoid valve be reduced to work along with strain gauges?

We are working with solenoid valves along with some strain gauges adjacent to them and trying to record strain data, but due to magnetic field generated by solenoid valve, we have been...

How can I stabilize an unstable FE analysis of a nonlocal damage model?

Nonlinear static problems can be unstable. Such instabilities may be of a geometrical nature, such as buckling, or of a material nature, such as material softening. If the instability manifests...

Is there any relationship between shear strength and tensile strength of a metal?

I would like to know if there is any relationship between shear and tensile strength of metals, and can we relate them with von Mises theorem or not? Can we use the von Mises theorem for ultimate...

How does one analyse data after Split Hopkinson Pressure Bar test?

I have done a Split Hopkinson pressure bar test and obtain two figures: one voltage of the inlet bar in time and the other one voltage of outlet bar in time. How i can obtain Force-displacement,...

Can someone advise on whether the strain in tensile testing is linear to time?

Research was carried out on the static tensile testing machine, which records only the loading force and displacement. I know the time needed to carry out the test, but while analyzing data I...

Did anyone work with diferencial image corelation programs

I wish to test some material with tensile testing machine, and capture film of it, with CCD camera, but do not know which camera to use for filming, so I can later use DIC on the recorded video....

Are uniaxial compression tests with samples of diameter between 25 and 50 mm good for calculating the deformation modulus (E) of an intact rock?

I am interested in papers and articles that discuss the possibility of using samples of diameter between 25 and 50 mm in Uniaxial compression tests in order to calculate the deformation modulus...

Why Calendaring Pressure is mentioned in N/mm?

I am using  a pneumatic calendaring machine from a popular manufacturer. The unit of pressure is mentioned in N/mm rather than N/mm2. I assumed that the point of contact of the roller with the...
