Yield strength - 13.8 MPa
Ultimate tensile strength - 31 MPa
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
Stress is a measure of the load applied to a sample relative to a cross sectional area of the sample. Strength is a quantification of the samples ability to carry a load. The terms "yield strength" and "yield stress" of a material are usually used interchangeably (correct or not). It is the stress which will just cause the material to plastically deform. If a material yields at 30,000 psi, the yield stress is 30,000 psi. If the part in question has a cross sectional area of 2 square inches, the strength at yield would be 60,000 pounds, but usually we just say the yield strength is 30,000 psi.
520 Mpa
It is its yield stress which is equal to 235 N/mm2
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
The breaking strength is always greater than the yield strength.
what is characteristic yield strength

Yes it is the same. Offset Yield strength = 0.2% Proof Stress
Tensile yield point or yield strength
The yield strength in this case is equal to the ultimate tensile strength, which is about 0.9-3 MPa without any reinforcement.
From multiple layers of veneer glued together.
Plywood is made in layers running it opposite directions which give it much more strength than a board that really only has strength in the direction of the grain.
Plywood is a type of manufactured wood made from thin sheets of wood. It is then glued together for greater strength. A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength.
Yield strength is the maximum stress a material can withstand without undergoing permanent deformation, while tensile strength is the maximum stress a material can withstand before breaking. In other words, yield strength represents the point at which a material changes from elastic deformation to plastic deformation, while tensile strength represents the maximum stress a material can handle before rupturing.
Yield strength is the point at which a material begins to deform permanently, while tensile strength is the maximum stress a material can withstand before breaking.
