Se empleó un barrido mediante tomografía computarizada para la generación de la imagen tridimensional de la mandíbula del dinosaurio carnívoro Carnotaurussastrei. Esta técnica no invasiva proporciona una base adecu...

The reliability of oil and gas transportation depends heavily on weld quality during pipeline construction. This study investigates the effect of gas metal arc welding (GMAW) current on API 5 L GrB pipeline weld joint. W...

The use of numerical methods, such as finite element method (FEM), has been widely adopted in solving structural problems with complex geometry under external loads when analytical solutions are unachievable. Basic idea ...

In the present study, the transmission error (TE) behaviour of an identical involute spur gear pair dynamically coupled with an attached subsystem is investigated through numerical modelling. The surrounding mechanical s...

Abstract This paper presents a digital model for the powder metallurgical (PM) production chain of high-performance sintered gears based on an integrated computational materials engineering (ICME) platform. Discrete and ...

An actual problem of stress-strain state (SSS) analysis of a bent metal plate under an uncertain acting load is solved.  A problem in the direct use of spatial interpolation for obtaining the surface of a metal plate,...

Abstract Re-entrant auxetic lattices exhibiting negative Poisson’s ratio behaviour are attractive for lightweight energy-absorbing applications. However, traditional re-entrant and hexagonal auxetic designs often exhib...

Abstract The footpad structure of a deep space exploration lander is a critical system that makes the initial contact with the ground, and thereby plays a crucial role in determining the stability and energy absorption c...

The present work investigates the compressive mechanical response of three lattice structures manufactured via VAT photopolymerization. A bio-inspired architecture, derived from the observation of Euplectella aspergillum...

It is a critical part at the basic design phase of aircraft structural design to build a finite element model and it will have a direct impact on time and cost for airframe structure development. In addition, the objecti...

Abstract According to relevant airworthiness standards, the aircraft fuel tank access cover must withstand the impact by tire fragments, and minimize the penetration and deformation, which is critical for flight safety. ...

The objective of this paper is to present a model to estimate actual evapotranspiration ETA from reference evapotranspiration ET0 by numerical modelling of water flow in the unsaturated zone of the soil. Water flow is de...

This work introduces a novel geometrical and analytical modeling framework for predicting the stiffness properties of knitted composites, a class of materials known for their complex architectures and versatile mechanica...

Abstract High strength steel products with good ductility can be produced via Q&P hot stamping process, while the phase transformation of the process is more complicated than common hot stamping since two-step quenching ...

The purpose of the present paper is to propose a novel approach of impact test system based on electromagnetic loading (EML) technology, which could provide more efficient and flexible experiment method with large range ...
