How do you find the loss factor in hysteretic damping?

Loss factor is best obtained by dynamically loading (extensional, torsional etc.) a specimen of the material and plotting the hysteresis curve in stress-vs strain plane. If the total area under the hysteresis loop is D, the loss factor is computed from the following formula Loss factor=D/(2*pi*max stress* max strain) For lightly damped materials, loss factor is just twice the daming factor 'zeta' which obtained either by log-decrement method or half-power bandwidth method.

What is hysteresis loop in stress and strain?

the leading or lagging between the stress and strain is called hysteresis loop

The area of hysteresis loop in a ferromagnetic material of?

The area of the hysteresis loop in a ferromagnetic material represents the energy losses that occur during the magnetization and demagnetization processes. It is a measure of the energy dissipated as heat due to the magnetic domain reorientation within the material. The larger the area of the hysteresis loop, the greater the energy losses and the lower the efficiency of the material in applications such as transformers or inductors.

Formula of Hysteresis loss and Eddy current loss?

hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity

How can you measure the hysteresis loop of the ferroelectric materials and what is the name of the instruments used for the measurements of the hysteresis loop?

The hysteresis loop of ferroelectric materials can be measured using a ferroelectric tester or a precision impedance analyzer. These instruments apply a voltage sweep to the material and measure the resulting polarization response, capturing the hysteresis loop which shows the relationship between polarization and applied electric field.

How do you determine the work done in a ferromagnet in going round a hysteresis loop?

When a hysteresis loop is plotted on a graph ( X: Current, Y: Magnetic Field Strength ) for the core of any substance, the area covered by the loop (on both sides of the x-axis) will give the total energy involved or work done in one cycle of magnetisation and demagnetisation.

How do you calculate hysteresis?

max hysteresis = max(O_decreasing - O_increasing) / (O_max - O_min)

Why area of hysteresis loop is change with temperature?

The area of the hysteresis loop changes with temperature because the magnetic properties of materials are temperature-dependent. As temperature increases, the alignment of magnetic domains can be affected, leading to changes in magnetic behavior. This can result in a shift in the hysteresis loop, impacting its area.

How do you select core in Transformer Design?

The material used in the manufacture of transformer cores must have a hysteresis loop with a very small area, as it is the area of the hysteresis loop that determines the hysteresis losses of the core material. The core material should also be resistive, in order to reduce eddy current losses (which is further improved by laminating the core). Many transformer manufacturers use their own variations on what is basically a silicon-steel.A hysteresis curve, or loop, is a graph of flux density plotted against magnetising force, and basically describes the ease (or difficulty) with which the core material can be magnetised and demagnetised as the magnetising current changes magnitude and direction.

What is hysteresis calibration loop?

A hysteresis calibration loop involves measuring a system's response by varying an input signal both increasing and decreasing across a range. The hysteresis loop indicates any lag or difference in the system's output when the input signal is reversed. It helps in understanding the system's nonlinear behavior and can be used to correct for any discrepancies in the system's operation.

How do you calculate the Hysteresis loss given a B-H curve?

hysteresis loss= K B^1.6 egs/sec where k is STEINMEITZ coefficient and B is the maximum magnetic flux density

How do you reduce the hysteresis loss?

Hysteresis losses are a function of the magnetic characteristics of the magnetic circuit, so there is very little you can do to minimise hysteresis losses other than to reduce the primary voltage to a transformer if that is at all practicable. These losses are really in the hands of the manufacturers who design and manufacture magnetic circuits.

What is the significance of looping?

In hysteresis materials it represents the energy dissipated in them during the cycle of magnetization & demagnetization (just refer any hysteresis loop diagram) . This is used in many applications especially in aerospace to damp the oscillations in satellite.
