Microstructural, mechanical, and thermal-shock behavior of hot-gas candle fiters obtained from different manufacturers have been evaluated. These filters include both monolithic ceramic and composite materials. Based on the results obtained so far, composite filters perform better than monolithic ceramic filters in a thermal-shock environment. During thermal-shock testing, the monolithic cerami...

A phase-field model of a crack front propagating in a three-dimensional brittle material is used to study the fractographic patterns induced by the branching instability. The numerical results of this model give rise to crack surfaces that are similar to those obtained in various experimental situations. Depending on applied loading configurations and initial conditions, we show that the branch...

The effect of shear stress on the dynamic failure ceramic materials is not sufficiently investigated in published literature. With use a bespoke split Hopkinson pressure bar, this paper presents an effort to investigate compressive response Macor, model material with zero porosity and light weight characteristics. A cone specimen cylindrical specimens varying inclined angles are used introduce ...

Abstract Martensitic 9% Cr steels like P91 and P92 can show an increased susceptibility to delayed hydrogen-assisted cracking. The focus of this study was the microstructure heat treatment effect on mechanical properties base material multi-layer weld metal in both as-welded post treated (PWHT) condition. Tensile tests with hydrogen-free reference samples electrochemically hydrogen charged were...

The aim of the present work is to contribute characterization biaxial tensile behavior commercially pure titanium, under various in-plane loading conditions at room temperature, by a non-contact digital image correlation system. Several conditions, with load ratio ranging from 4:0 0:4 and displacement rate 0.001 0.1 mm/s, are examined. It found that yield strength ultimate sample greater than u...

Abstract Lattice materials are a subset of cellular solids with periodic microstructure and interest in number applications because their potential weight‐saving properties. In this study, circular lattices machined out plates made Ti‐6Al‐4V fatigue tested to generate an S–N curve. These results compared FEM data based on MIL‐HDBK‐5H. A good agreement the was found, suggesting that life can be ...

The fatigue behavior of bolted joints is critical to failure for many applications due the high notch effect. Among other parameters, lifetime based on influence surface system, consisting corrosion protection and lubricant. With intention considering system in design dimensioning process joints, experimental investigations are carried out systematically an exemplary selected basecoat various l...

The influence of the ultrafine-grained structure formed by equal-channel angular pressing via “Conform” scheme on fatigue behavior metastable β-alloy Ti-15Mo has been studied. It is shown that alloy with a two-phase achieved best mechanical properties and enhanced endurance limit (up to 710 MPa basis 107 cycles) due total contribution grain boundary, dislocation, phase strengthening mechanisms....
