The gravitational field effect on a micro-elongated thermoelastic layer under a fluid load with two theories

Mohamed I.A. Othman, Mohamed F. Ismail

This paper aims to study the gravity effects on a micro-elongated thermoelastic layer under a fluid load, utilizing the Lord–Shulman (L-S) theory and the dual-phase-lag (DPL…

Effect of freeze-thaw damage at curing time on mechanical properties of polyurethane concrete

Hongyang Wang, Quansheng Sun

Polyurethane concrete has a high strength-to-weight ratio in the short term, and the strength-to-weight ratio stage during the maintenance period is critical. Freeze-thaw cycles…

A novel model on nonlocal thermoelastic rotating porous medium with memory-dependent derivative

Samia M. Said, Mohamed I.A. Othman, Mohamed G. Eldemerdash

In the present article, the three-phase-lag (3PHL) model and the Green-Naghdi theory of types II, III with memory-dependent derivative is used to study the effect of rotation on a…

Investigation on vibration parameters in aluminum finned tube arrays subjected to water cross flow

Pravin H. Yadav, Sandeep R. Desai, Dillip Kumar Mohanty

Predicting the critical velocity is crucial at the instability threshold for shell and tube heat exchangers in order to prevent tube failure due to vibrations. In this study, the…

Memory impact of hygrothermal effect in a hollow cylinder by theory of uncoupled-coupled heat and moisture

Jyoti Verma, Navneet Kumar Lamba, K.C. Deshmukh

The purpose of the paper is to prepare the hygrothermal model with fraction order theory in a mathematical aspect.

Predicting thrust force during drilling of composite laminates with step drills through the Gaussian process regression

Yun Zhang, Xiaojie Xu

Here, the authors use step angles, stage ratios, feed rates and spindle speeds as predictors to develop a Gaussian process regression for predicting thrust force during composite…

Enhancement of local concrete compression performance by incorporating ultra-high performance concrete (UHPC) tube

Lifeng Wang, Haiqi Wu, Long Liu, Ziwang Xiao

The application of ultra-high performance concrete (UHPC) in anchorage zones can significantly improve the local compression performance of structures. However, the high cost and…
