uniaxial stress मीनिंग इन हिंदी

Uniaxial tests do not provide lateral restraint during testing and thus tests the sample under uniaxial stress conditions.
They are called the shrinkage ( typically causing strains between 0.0002 and 0.0005, and in low strength concretes even 0.0012 ) or swelling ( J ( t, t'), defined as the stress-produced strain \ epsilon ( i . e ., the total strain minus shrinkage ) caused at time t by a unit sustained uniaxial stress \ sigma = 1 applied at age t', is measured as the strain difference between the loaded and load-free specimens.
