These are size-independent measures of load and displacement, respectively. Modulus of elasticity Yield strength Tensile strength Modulus of resilience Failure stress Ductility Toughness Modulus of elasticity - the initial slope of the curve, related directly to the strength of the atomic bonds. The energy needed to break a unit volume of material. Regangan merupakan besaran tanpa satuan. The deformation is no longer reversible. Ductility - the total elongation of the specimen due to plastic deformation, neglecting the elastic stretching the broken ends snap back and separate after failure. The plastic strain at failure.

Regangan arah z dapat dihitung dengan persamaan: Failure stress - the stress applied to the specimen at failure usually less than the maximum tensile strength because necking reduces the cross-sectional area. These are size-independent measures of load and displacement, respectively. To minimize deformation, select a material with a large elastic modulus E or G.
Tegangan yang diberikan dapat dihitung dengan Hukum Hooke: The elastic portion of the curve is not perfectly linear, and microscopic amounts of deformation can occur. Anderson photo courtesy P. Gaya yang harus diberikan: As a matter of practical convenience, the yield strength is determined by constructing a line parallel to the initial portion of the stress-strain curve but offset by 0.
Regangan merupakan besaran tanpa satuan.
SIFAT MEKANIS 1.
Pressurized tank photo courtesy P. Yield strength, usually defined as the point at which a consistent and measureable amount of permanent strain remains in the specimen.
The energy needed to break a unit volume of material. Note that engineering stress uses the pppt area, regardless of the change in diameter during the tensile test.

Regangan arah z dapat dihitung dengan persamaan:. III, Mechanical Behavior, p. Konsep tegangan dan regangan.
Modulus of elasticity - the initial slope of the curve, related directly to the strength of the atomic bonds. The area of a stress - strain curve where the specimen will deform under load, yet return to its original shape when the load is removed.

The plastic strain at failure. Note that engineering stress uses the initial area, regardless of the change hukun diameter during the tensile test.
Modulus of elasticity Yield strength Tensile strength Modulus of resilience Failure stress Ductility Toughness Modulus of elasticity - the initial slope of the curve, huum directly to the strength of the atomic bonds.
Several measurements are taken from the plot, called the Engineering Stress-Strain Diagram. All three failed under tension Tensile Test Stress Strain Diagram The applied stress versus the strain or elongation of the specimen shows the initial elastic response of the material, followed by yielding, plastic deformation and finally necking and failure.
As a matter of practical convenience, the yield strength is determined by constructing a line parallel pt the initial portion of the stress-strain curve but offset by 0.
Several measurements are taken from the plot, called the Engineering Stress-Strain Diagram. The intersection of this line and the measured stress-strain line is used as an approximation of the material's yield strength, called the 0. The plastic strain at failure. Log In Sign Up.
