The paper aims to determine the mechanical properties of adhesive joints made with acrylic pressure-sensitive adhesives. Two types double-sided tapes are used. Three construction materials used prepare joints: structural steel sheet (C45), aluminium alloy (EN-AW 5754), and titanium (Grade 2). Strength tests carried out both after conditioning time at room temperature (23 °C) subjected thermal s...

Elastic abrasive cutting is a new high-performance method to produce workpieces made of materials different hardness, which ensures lower wear cut-off wheels and higher quality machined surfaces. However, the literature referring elastic scarce; additional studies are thus needed. This paper proposes approach for modelling optimizing process, reflecting specifics its particular implementation. ...

This paper analyzes the impact of intermediary concentration on allocation revenue in online platforms. We study sponsored search documenting how advertisers increasingly bid through a handful specialized intermediaries. enhances automated bidding and data pooling, but lessens competition whenever represents competing advertisers. Using nearly 40 million Google keyword auctions, we first apply ...

A nonlinear model is proposed in light of the theory isodamage curves, to assess cumulative fatigue damage under multistage loading. The curves were developed through S-N envelope, by Pavlou. adopted functional form a commonly accepted general form. In present work, stress function for life exponent derived with aid curve only. model, no adjusting parameters are necessary estimation. prediction...

In the present work, dissimilar joints between C45 carbon steel and nickel-chromium 16NiCr6 rods were produced using rotary friction welding process. Statistical analysis based on response surface methodology (RSM), microstructural examination scanning electron microscopy with backscattered diffraction (EBSD) mechanical tests performed to investigate weld joints. The results showed that time ro...

Inverse problems can be challenging and interesting to study in the context of metallurgical processes. This work aims carry out a method for inverse modeling simultaneous double-frequency induction hardening process. In this investigation, experimental measured hardness profiles were considered as input data, while output data process parameters. For purpose experiments carried on C45 steel sp...
