In this study, a new traction-separation based constitutive model for use in finite element simulation of masonry joints under complex loading conditions is developed cohesive elements. The proposed formulated using damage parameters and plastic deformation with mutual couplings, can accurately simulate the nonlinear behaviors considering hardening or softening strength stiffness degradation. T...

self-centering pier (scp) has been viewed as a remarkable accomplishment which is able to sustain major lateral loading with reduced structure damage in seismic engineering. stiffness deterioration observed in experiment is vital for the seismic performance of self-centering concrete pier. in this contribution, the associated stiffness deterioration with respect to the structural damage is mode...

The effect of gradient microstructure generated by ultrasonic surface mechanical attrition treatment (SMAT) on the fatigue performance an austenitic stainless steel has been evaluated in context localized and general plasticity comparing two load ratios: fully reversed tension-compression (TC) RTC = -1 tension-tension (TT) RTT +0.1, respectively. After identical SMAT processing conditions, limi...

The currently available anti-buckling fixtures for uniaxial tension-compression testing of sheet metal could not fulfill the requirements and standards. In this study, a unique system to enable getting accurate repeatable isotropic kinematic behavior was designed. front surface specimen fully supported during initial position, tension, compression free from any buckling. Because using acrylic b...
