I have few general queries regarding MLPG meshfree method

1. Can the trial and test functions be taken same for solving a problem

2. In the problem if there are zones with different properties, for example different Coeffiencient of Permeability in the aquifers (Plan view-wise), how to handle the interface between the zones and assemble the global matrix

Easily calculate longitudinal compression strength of unidirectional composites

Submitted by ebarbero on

The longitudinal compression strength of unidirectional composites F1c, also called Xc, is very difficul to test for, so often you don't have the value for the particular material (fiber, matrix, volume fraction) that you wish to use. Further, just having data does not tell you what paramaters really influence its value--it is not the compressive strength of the fiber, I can assure you. So, there is a simple formula that you can use to predict its value and also to understand what are the parameters that really affect the compression strength of the composite.

where to go for the computational modelling?

Submitted by Wei Ong on

This post is to share where to go for the computational modelling. Should computation modelling focus on advance the solver convergence or focus on experiment verification?

The experiment verification always expensive and high cost involved. For solver convergence, it is always take time but less cost involved, however even with advance computational power and smart equation, we always face problem on verfiy our result through experiement stage.
