A study on shrinkage residual stresses, microstructure and mechanical properties of ASS thick pipe welded by GMAW process

Materials Research Express, 2021
In this investigation, AISI 304LN austenitic stainless steel pipes having 25 mm thickness and 300 mm inner diameter with conventional and narrow groove were welded by continuous current gas metal arc welding (GMAW) and pulse current gas metal arc welding

Orthotropic hygro-mechanical behavior of Chinese fir during cyclical relative humidity variation

Journal of Wood Science, 2020
The orthotropic free swelling–shrinkage and mechano-sorptive creep (MSC) during cyclical relative humidity (RH) variation (0–80% RH) and time-dependent viscoelastic creep (VEC) in a steady state (0% RH) were examined in Chinese fir (Cunninghamia ...

Shrinkage Properties and Their Relationship with Degradation of Proteins Linking the Endomysium and Myofibril in Lamb Meat Submitted to Heating or Air Drying

Foods, 2022
The shrinkage of the connective tissue and myofiber of lamb meat submitted to heat treatment or air drying at different storage stages (1, 5 and 7 days) was evaluated herein. The longitudinal and transverse shrinkage of heated lamb meat was significantly

Design, fabrication, and characterization of a hydrostatic electroactive soft actuator for bio-inspired robots

Biomimetic Intelligence and Robotics, 2022
In this paper, we design a hydrostatic electroactive soft actuator (HESA) inspired by octopus transverse musculature. We introduce the advantage of laser processing technology in HESA fabrication compared with existing similar actuators and discuss the ...

Effects of power modulation on behaviours of molten pool and keyhole during laser–arc hybrid welding of pure copper

Materials & Design, 2020
Modulated laser power hybrid welding (M-HW) of 4 mm-thick T2 pure copper was conducted to improve the welding stability. It was observed that the sinusoidal modulation of laser power in hybrid welding can reduce the incidence of weld defects such as ...

Investigation of drying shrinkage effects on sloped concrete-concrete composites [PDF]

, 2022
Multi-layer concrete systems have been widely used in bridge decks, rigid pavements, and floors. The restrained drying shrinkage of the overlay is of great concern as it can lead to overlay cracking and/or interfacial debonding.

Modeling the Cupping of Lumber

BioResources, 2016
Wood shrinks anisotropically as it loses hygroscopic moisture. While longitudinal shrinkage (parallel to the grain) is nearly negligible in normal wood, transverse shrinkage (across the grain) is significant and characterized as tangential and radial ...

Determination of residual stress evolution during repair welding of high-strength steel components

Forces in Mechanics, 2022
During the assembly of steel structures, unacceptable weld defects may be found. An economical solution is local thermal gouging of the affected areas and re-welding.

Application of a Novel Chamfered Mold to Suppress Corner Transverse Cracking of Micro-Alloyed Steel Slabs

Metals, 2020
A novel chamfered mold is developed to solve the problem of corner transverse cracking in micro-alloyed steel slabs. The shape of the slab was changed from four corners and sides to eight corners and sides due to the use of a chamfered mold.
