PC Based Online Strain Measurement Analysis

Pc based strain measurment analysis on concrete cube
we do strain measurement of concrete structure using strain gauges and daq acquisition card along
with software and graphical representation with more accuracy in depth we have two to eight channel
systems(as per your requirement).
The poisson's ratio n of a material is defined as the negative ratio of the stain in the transverse direction
(perpendicular to the force) to the strain in axial direction (parallel to the force), or n= ete. Poisson's
ratio for steel, for example, ranges from 0.25 to 0.3.
Strain can be positive (tensile) or negative (compressive).although dimensionless, strain is sometimes
expressed in units such as in.in. Or mmmm. In practice, the magnitude of measure strain is very
small. Therefore, strain is often expressed as micro strain (me), which is e x 10-6.
Advantages
1. In the strain analysis, you can exactly find out where the deformation starts at first.
2. We need to give 40% of load for a particular time in a cyclic method and find out
complete characteristics of your concretes cubes.
3. You can find the strain value in percentage.
4. You can also conduct advanced tests like poisson ratio and youngã¢ï¿½ï¿½s modulus as per is 516
standard.
5. You can get online graphs like stress versus strain, load versus time, strain versus time,
multiple strain graphs etc....
