Abstract The influence of pre-strain on the very-low-cycle loading behavior as occurring, for example during roller leveling sheet metals, is not yet fully understood. A key factor in this context stiffness material and its changes upon processing. To study general mechanical property low-cycle with small amplitudes a wide variety samples mild steel DC01, pure copper CU-DHP α -titanium are subj...

To investigate the hot deformation behavior of 17-7 PH stainless steel, hot compression tests were carried out at the temperatures of 950, 1050 and 1150 oC and strain rates of 0.001 s-1 to 0.1 s-1. Accordingly, the hot working behavior was studied by the analyses of flow stress curves, work hardening rate versus stress curves, exponent- type constitutive equations and deformed microstructures. ...

Time-dependent creep analysis is presented for the calculation of stresses and displacements of axisymmetric thick-walled cylindrical pressure vessels made of functionally graded material (FGM). For the purpose of time-dependent stress analysis in an FGM pressure vessel, material creep behavior and the solutions of the stresses at a time equal to zero (i.e. the initial stress state) are needed....

Introduction—Spinal ligaments play an important role in spine biomechanics. Accordingly, a precise understanding of ligament mechanical properties is requisite for accurate modeling of the local and global behavior of the spine. Spinal ligaments exhibit nonlinear stressstrain relationships and viscoelastic material behavior. Current literature on the viscoelastic response of cervical spine liga...

The forced vibration behaviors are examined for nonlocal strain gradient nanobeams with surface effects subjected to a moving harmonic load travelling with a constant velocity in terms of three beam models namely, the Euler-Bernoulli, Timoshenko and modified Timoshenko beam models. The modification for nonlocal strain gradient Timoshenko nanobeams is exerted to the constitutive equations by exc...
