The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...
The Timoshenko–Ehrenfest beam theory was developed by Stephen Timoshenko and Paul Ehrenfest [1] [2] [3] early in the 20th century. [ 4 ] [ 5 ] The model takes into account shear deformation and rotational bending effects, making it suitable for describing the behaviour of thick beams, sandwich composite beams , or beams subject to high ...
Stepan Prokopovich Timoshenko [3] (Ukrainian: Степан Прокопович Тимошенко, romanized: Stepan Prokopovych Tymoshenko; Russian: Степан Прокофьевич Тимошенко, romanized: Stepan Prokofyevich Timoshenko, [sʲtʲɪˈpan prɐˈkofʲjɪvʲɪtɕ tʲɪmɐˈʂɛnkə]; December 22 [O.S. December 10] 1878 – May 29, 1972), later known as Stephen ...
Strength of Materials (Russian: Проблемы прочности) is a bimonthly peer-reviewed scientific journal covering the field of strength of materials and structural elements, mechanics solid deformed body.
He was awarded the Timoshenko Medal in 1972 "in recognition of distinguished contributions to the field of applied mechanics." In 1987 the Design Division of ASME announced the establishment of the J. P. Den Hartog Award for "sustained meritorious contributions to vibration engineering" at its eleventh vibration conference; Den Hartog himself was the first recipient.
A solid is a material that can support a substantial amount of shearing force over a given time scale during a natural or industrial process or action. This is what distinguishes solids from fluids, because fluids also support normal forces which are those forces that are directed perpendicular to the material plane across from which they act and normal stress is the normal force per unit area ...
The maximum stress criterion assumes that a material fails when the maximum principal stress in a material element exceeds the uniaxial tensile strength of the material. Alternatively, the material will fail if the minimum principal stress σ 3 {\displaystyle \sigma _{3}} is less than the uniaxial compressive strength of the material.
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
