That is stress in three dimensions. Biaxial stress is in two dimensions.
Triaxial stress has normal and shear stresses along each of three planes. Most beams can be analyzed with uniaxial stress; plates with biaxial; solids with triaxial

What are the difference between result obtained from ultrasonic test and triaxial test?
Triaxial testing will yield static strength properties of the material while ultrasonic measurements will give dynamic strength properties. The two can be related to each other by using various relationships between Young's Modulus, Bulk Modulus, Shear Modulus and Poisson's ratio. Static results should be lower than the dynamic results.
How do you draw 2 dimensional yield surface in deviatoric plane or pi plane?
Strictly speaking, in 2D it is a yield line, not a surface (you would have to do a £D plot for that). In order to construct a deviatoric yield surface plot you require the triaxial data for a sample for at least three differing confining pressures. You will then essentially be creating a series of mohr circle plots (shear stress vs Sigma1 - Sigma3) of the deviatoric stress circles at the failure stress of the samples. A straight line is then drawn that touches the upper bounds of the three circles without passing through them. This line is the 2D deviatoric yield plot. There is free software available that will do this for you. Please see the related links.
What is consolidated drained triaxial test?
In a consolidated drained test the sample is consolidated and sheared in compression with drainage. The rate of axial deformation is kept constant, i.e. is strain controlled. The idea is that the test allows the sample and the pore pressures to fully consolidate (i.e. adjust) to the surrounding stresses. The test may take a long time to allow the sample to adjust, in particular low permeability samples need a long time to drain and adjust strain to stress level
What are the difference kinds stress?
Normal stress and shear stress
What is the relation between yield stress and allowable stress?
A factor of safety against yield is applied to design stress Yield Stress/ Design Stress = Factor of safety The factor of safety varies for different industries; 1.5 is used in structural steel design for buildings; 1.25 or even 1.1 for aircraft/space systems
Differences between triaxial test and shear box test?
Shear box tests are generally suitable for cohensionless soil except fine sand and silt whereas triaxial test is suitable for all types of soils. Pressure changes and volume changes can be measured directly in triaxial test which is not possible in shear box test. Pore water pressure can be measured in the case of triaxial test which is not possible in direct shear test. Triaxial machine is more adaptable. The stress distribution across the soil sample in the failure plane is more uniform in triaxial test. The complete state of stress is known at all intermediate stages up to failure during the triaxial test whereas only the stress at failure are known in the direct shear test. In triaxial test, there is complete control over the drainage conditions, where control of drainage conditions is very difficult in shear box test.
Which of the following is an example of a triaxial joint?
Ball-and-socket joint is an example of triaxial (or multiaxial) joint.

Which stress is defined as that degree of stress which is necessary to sustain and improve tolerance to stress without overdoing the stress experience?
mental stress
What stress is defined as that degrees of stress which is necessary to sustain and improve tolerance to stress without overdoing the stress experience?
Positive stress
What stress is defined as that degree of stress which is necessary to sustain and improve tolerance to stress without overdoing the stress experience?
Positive stress
What is the definition of stress management?
The definition of stress management is to control stress. Good stress management provides a healthy way to relieve stress.
