Whether the measurement results are reliable depends mainly on two aspects:
1.Whether the colloidal material can ensure the durability of the strain gauge and the connected object. At present, the commonly used epoxy resin adhesive and 502 adhesive generally have the disadvantages of high bonding strength and poor ductility, and are obviously not suitable for the low elastic modulus and low strength flexible material of geotextile. This indicates that the resistance strain gauge measurement method needs to be improved or improved when used for wholesale long fibre filament needle punched geotextile deformation measurement.
2.Whether the colloid attached to the strain gauge can ensure that the strain gauge and the measured object are co-deformed, that is, the stiffness of the colloidal material should be less than the measured object. Alisajune Thomas / |
