Beban dilepas Elastic means reversible! 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. Regangan arah z dapat dihitung dengan persamaan:. The elastic portion of the curve is not perfectly linear, and microscopic amounts of deformation can occur. This reversible behavior often shows a linear relation between stress and strain. Enter the email address you signed up with and we'll email you a reset link.

(PPT) (sifat mekanik) | Gilang Pratama -

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. Tegangan yang diberikan dapat dihitung dengan Hukum Hooke: By Rizki Zakaria Manalu Manalu.

The deformation is no longer reversible. The plastic strain at failure. Pressurized tank photo courtesy P. Regangan merupakan besaran tanpa satuan. Ductile Ductile Adapted from Fig. III, Mechanical Behavior, p. This permanent deformation behavior occurs when the tensile or compressive uniaxial stress reaches sy.

III, Mechanical Behavior, p. Modulus of elasticity - the initial slope of the curve, related directly to the strength of the atomic bonds.

The elastic portion of the curve is not perfectly linear, and microscopic amounts of deformation can occur. Remember me on this computer. This reversible behavior often shows a linear relation between stress and strain. These are size-independent measures of load and displacement, respectively. The elastic hookee of the curve is not perfectly linear, and microscopic amounts of deformation can occur.

Dengan memasukkan harga — harga: These are size-independent measures of load and displacement, respectively. The localized decrease in diameter in a specimen near the rupture point. Regangan arah z dapat dihitung dengan persamaan: Kurva tegangan regangan dan intepretasinya. To minimize deformation, select a material hukmu a large elastic modulus E p;t G.

Pressurized tank photo courtesy Fish under water P. Pada deformasi elastis, hubungan antara tegangan dan regangan adalah: 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.

Mengenal Sifat Material Advertisements.

SIFAT MEKANIS 1.

Note that engineering stress uses the initial area, regardless of the change in diameter during the tensile test. Sifat elastis dan sifat plastis material.

You're using an out-of-date version of Internet Explorer. Regangan arah z dapat dihitung dengan persamaan:. Anderson photo courtesy P.

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. Hitung beban yang diperlukan untuk menghasilkan perubahan diameter 2,5 x mm, jika deformasi yang terjadi adalah deformasi elastis: 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.
