Depth-dependent ratcheting strains of young and adult articular cartilages by experiments and predictions

open access: yesBioMedical Engineering OnLine, 2019
Background Ratcheting strain is produced due to the repeated accumulation of compressive strain in cartilage and may be a precursor to osteoarthritis.

Compressive fatigue behavior of graded tantalum scaffolds produced by electron beam powder bed fusion

open access: yesJournal of Materials Research and Technology, 2023
In this study, graded tantalum scaffolds were manufactured by electron beam powder bed fusion (EB-PBF). Compression-compression fatigue testing was conducted on the EB-PBF built graded tantalum scaffolds.

Study of Cyclic Plasticity and Creep Ratchet Behavior of PTFE

open access: yesApplied Sciences, 2023
Due to its superior corrosion resistance and low coefficient of friction, polytetrafluoroethylene (PTFE) is extensively used in the aerospace, machinery, chemical, and pharmaceutical industries. However, PTFE components encounter complex alternating stresses, resulting in ratchet and creep, which will affect the component’s reliability. It is therefore

Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture

open access: yesAngewandte Chemie, EarlyView.
Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Viscoplastic Constitutive Equations for Ratchetting Behavior

open access: yesTransactions of Materials Processing, 2005
Inelastic deformation behavior of metals and alloys is considered rate dependent. Uniaxial ratcheting experiments performed by Ruggles and Krempl, and Hassan and Kyriakides exhibited that higher mean stress for a fixed stress amplitude resulted in higher ratchet strain within a rate independent framework and higher stress rate resulted in lower ratchet

Mechanical behavior of large-diameter pipe elbows under low-cyclic loading

open access: yesJournal of Sustainable Construction Materials and Technologies, 2023
Large-diameter steel pipes are often used for transmitting and distributing water, gas, and oil products from the source to the end user. These pipelines are mainly oriented by using pipe el- bows due to their high flexibility along their routes.
