Gerilim ve Zorlanma - Eksenel Yükleme

Eksenel Yükleme Altında Normal Gerinim
Eksenel Yükleme Altında Normal Gerinim
A rod subjected to a load undergoes elongation. A load-deformation diagram can represent the elongation but cannot predict deformation in different rods. ...
Gerilim-Gerinim Diyagramı
Gerilim-Gerinim Diyagramı
Consider a cylindrical specimen placed in a system to measure its tensile strength. Two gauge marks are inscribed on the central portion of the specimen. ...
Gerilme-Gerinim Diyagramı - Sünek Malzemeler
Gerilme-Gerinim Diyagramı - Sünek Malzemeler
When a specimen is subjected to loading the length first increases linearly at a slow rate, resulting in an initial straight line with a steep slope on ...
Gerilim-Gerinim Diyagramı - Kırılgan Malzemeler
Gerilim-Gerinim Diyagramı - Kırılgan Malzemeler
Brittle materials, under tensile stress, do not elongate much before rupturing, meaning their ultimate and breaking strengths are identical. Compared with ...
Gerçek Gerilme ve Gerçek Gerinim
Gerçek Gerilme ve Gerçek Gerinim
Engineering stress is the ratio of the load and the undeformed original cross-sectional area. Engineering stress approximates strain which represents the ...
Hooke Yasası
Hooke Yasası
Hooke's law states that stress applied to a material is directly proportional to the strain it experiences within the elastic limit. For ductile ...
Plastik Davranış
Plastik Davranış
Materials under stress due to tensile loading exhibit elastic and linear behavior until the yield point. Removing the load at the yield point, stress and ...
Yorgunluk
Yorgunluk
Fatigue occurs when the materials, under repeated loads for thousands or millions of cycles, rupture at a stress level much lower than the material's ...
Elemanın Çoklu Yüklemeler Altında Deformasyonu
Elemanın Çoklu Yüklemeler Altında Deformasyonu
The deformation of a rod with different materials and cross-sections is computed by dividing it into parts, each characterized by individual parameters. ...
Statik Olarak Belirsiz Problem Çözme
Statik Olarak Belirsiz Problem Çözme
Consider two cylindrical rods, one of steel and another of brass, joined at point B and restrained by rigid supports at points A and C. Determine the ...
Termal Gerinim
Termal Gerinim
A homogeneous rod with a uniform cross-section, resting freely on a horizontal surface, expands when heated. The expansion is proportional to the ...
Sıcaklığa Bağlı Deformasyon
Sıcaklığa Bağlı Deformasyon
Consider a non-homogenous rod made of steel and brass, restrained at both ends and subjected to a temperature change. The stress and load on the rod are ...
Poisson Oranı
Poisson Oranı
When a slender bar is subjected to an axial load, the bar material undergoes axial strain, causing it to deform in the axial direction. Simultaneously, ...
Genelleştirilmiş Hooke Yasası
Genelleştirilmiş Hooke Yasası
The generalized Hooke's Law extends Hooke's Law to all stress types and directions, aiding in understanding materials under multiaxial stress ...
Yığın Modülü
Yığın Modülü
The bulk modulus measures a material's resistance to uniform compression. It is defined as the proportionality constant between a change in pressure ...
Kesme Gerinimi
Kesme Gerinimi
In a cubic element with a general state of stress, the shearing stresses can deform a cube into an oblique parallelepiped without affecting normal ...
Poisson oranı, Elastisite Modülü ve Rijitlik Modülü arasındaki ilişki
Poisson oranı, Elastisite Modülü ve Rijitlik Modülü arasındaki ilişki
A slender bar subjected to an axial load undergoes deformation in the axial and transverse directions. The deformation affects the cubic elements within ...
Saint-Venant Prensibi
Saint-Venant Prensibi
Consider a member with plates on both ends. When loads are applied centrally on the plates, they move towards each other without rotating, causing the ...
Stres Konsantrasyonları
Stres Konsantrasyonları
Stress concentration refers to the amplification of stress in a structural member near points of discontinuity, such as holes or abrupt changes in ...
Artık Gerilmeler
Artık Gerilmeler
When a rod is stretched beyond its yield point, it permanently deforms and doesn't regain its original length. The stresses created during loading are ...
