Difference between plane stress and plane strain problems
Answers
Plane stress applies to a sheet of material in which the stress in the thickness direction is much much lower than the stresses within the plane. The stress in the thickness direction is taken as zero.
Plane strain applies to a solid in which one of the principal strains is zero (typically as a result of the imposed boundary conditions). For example, if you had a sheet of material that could not strain in the thickness direction (constrained by boundaries above and below), and if the shear stresses imposed by these boundaries were also zero (slippery interface), you have a plane stress situation.
hope it help u .....
Answer:
plane stress means the stress we feel in plain work and plain stain means the stain mainly is called the garabages or the rubbished thing in our house.
