in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

We propose an extension to Nomarski differential interference contrast microscopy that enables isotropic linear phase imaging. The method combines phase shifting, two directions of shear and Fourier-space integration using a modified spiral phase transform. We simulated the method using a phantom object with spatially varying amplitude and phase. Simulated results show good agreement between th...

This paper presents a mechanical model of the shear resistance based on Critical Shear Crack Theory (CSCT) and its application for checking ultimate state self-stressed elements reinforced with FRP bars. The force, which is transmitted through inclined crack by aggregate interlock, residual tensile strength, dowel action chord compression concrete, calculated depending value opening, determined...

Curved bridge deck pavement materials are easy to be damaged due their complex stress conditions. Hence, the application of a high-viscosity modified asphalt mixture in curved is studied this paper. Firstly, severity diseases on decks was introduced and compared with straight sections. Then, SBS-modified SMA-13, advantages HM-SMA-13 resistance deformation, water damage, shear fatigue were analy...

Tests of deep concrete beams with internal fiber-reinforced polymer (FRP) reinforcement have shown that such members can exhibit lower shear strength than members with conventional steel reinforcement. To model this effect, the current paper proposes an approach based on a two-parameter kinematic theory (2PKT) for conventional deep beams. The 2PKT is built on a kinematic model with two degrees ...

Natural hydraulic lime soil has good mechanical properties; as an earthen ruin restoration material, its durability is insufficient. Despite natural being a topic that been studied for several years from different researchers, it not yet fully considered the improvement of durability. This work aims to experimentally investigate enhancement properties lime-based. The performance limestone by ad...

abstract statement of problem: there is no enough published data about the shear bond strength of resin modified glass ionomer adhesives on caries-affected primary tooth dentin excavated using minimally invasive systems. objectives: to evaluate the shear bond strength of 2 different adhesives (one resin modified glass ionomer and one resin) using two caries removal techniques on healthy and car...
