Abstract The change of the liner material directly affects penetration and damage performance shaped charge. In this paper, Ti-29Nb-13Ta-4.6Zr (TNTZ) was used as charge liner. Autodyn software to analyze jet formation TNTZ liner, then static explosion test conducted liners. following conclusions were obtained: A structure proposed for alloy, simulation shows that a with acceptable L/D ratio for...

The density and modulus of elasticity (MOE) distribution can provide information on the effectiveness parametric non-parametric methods in calculating characteristic value MOE. In this study, we aim to determine optimal model actual measured data lumber. We also estimate lumber’s MOE compare difference between natural planted larch. Approximately 1200 pieces dimension lumber 4 m × 140 mm 40 siz...

In order to reduce the amount of cement required, improve workability, mechanical properties, and durability, have a positive environmental impact, supplementary cementitious materials are frequently utilized as partial replacement for in concrete mixes. this experimental investigation, effects employing waterproof supplemental such flyash, silica fume, nano along with water reduction agent wer...

The aim of this work is to analyze the factors that help companies avoid liquidation following spirit Spanish insolvency law. This focuses on phase starting when file for bankruptcy and ending with completion common phase. We apply agency theory explain how administrators court characteristics influence outcome process (liquidation or reorganization). unique accounting data from 2,627 filed dur...

An experimental test was performed to study the bond behavior between steel rebar and concrete reinforced by polyvinyl alcohol (PVA) fibers. Twenty specimens were prepared subjected pull-out test. Four different fiber volume contents (0%, 0.2%, 0.4%, 0.6%) considered with strength grade of C35 designed in present study. The effects PVA fibers, diameter, cover depth on clarified. fibers mechanic...

Bar diameter is one of the basic factors affecting bond behavior, which still interest due to opposing opinions regarding its effect on behavior in pull-out test. This paper presents an experimental and numerical analysis ribbed reinforcing bar concrete. The aim was experimentally evaluate test perform simulations conducted experiments ABAQUS verify their convergence obtained results. used conc...

This article is a response to the state of art in monitoring cooling capacity quenching oils industrial practice. Very often, hardening shop requires report with data on process for particular oil. However, interpretation can be rather difficult. The main goal our work was compare various criteria used evaluating oils. Those which prove essential operation tempering plants would then introduced...
