15 окт. 2016 г. · Pressure is defined as the average of normal stresses on three orthogonal planes passing through the point where stress tensor is calculated.

25 февр. 2014 г. · Pressure is only based on the normal stress on the element, the stress tensor includes both normal and shear terms.

12 дек. 2014 г. · Pressure is part of the stress tensor. The diagonal elements form the pressure. For example, σxx measures how much x-force pushes in the x- ...

21 февр. 2023 г. · The off-diagonal terms in the pressure tensor, sometimes called the strain tensor or the viscosity terms, represent momentum transport across boundaries.

30 мая 2021 г. · It comes down to whether we consider the fluid incompressible or not. If the fluid is considered incompressible, then the pressure is not ...

4 нояб. 2016 г. · It can be derived from the virial theorem. The result is: Pij=V−1(∑kmkvikvjk+∑krikfjk). where V is volume, k is summed over all atoms in the ...

22 июн. 2018 г. · The diagonal components of the stress tensor are not each equal to pressure (or minus the pressure, depending on the sign convention used for the stress tensor)

6 дек. 2018 г. · A simple mathematical deduction shows that the flux in any direction of the momentum component in that direction must be non-negative.

18 апр. 2017 г. · In the stress energy tensor Tμν the flux of i-component of momentum in the i-direction is Tii. This is identified as the pressure. However for ...

19 февр. 2021 г. · I need to calculate the pressure autocorrelation function in a Brownian dynamics particle simulation to get the viscosity (which is ...
