3D Global Weak-Form Mesh-Free Method for Acoustic Attenuation Analysis of Expansion Chambers
Shock and Vibration, 2020 In order to avoid the dependence of mesh method on grids, a 3D global weak-form mesh-free method (MFM) is applied to study the three-dimensional acoustic characteristics of silencers.

A smoothed radial point interpolation method (S-RPIM) for large-deformation elasto-visco-plastic analysis occurring in sheet metal blanking processes [PDF]
, 2017 In this paper, a meshfree cell-based smoothed radial point interpolation method (CS-RPIM) is extended to large-deformation elasto-visco-plasticity analysis for simulation of high speed sheet metal blanking processes. For this purpose, two techniques included in large-deformation analysis formulation are employed: a Johnson?Cook flow stress model and an

A coupled Meshless-FEM method based on strong form of Radial Point Interpolation Method (RPIM)
Journal of Physics: Conference Series, 2021 Abstract In this present work, we are implementing a novel hybrid method based on the coupling of RPIM in strong form and Finite Element Method (FEM). The basic idea is to ensure the coupling between the two methods through the collocation technique based on RPIM interpolation.

Amber Light Control of Peptide Secondary Structure by a Perfluoroaromatic Azobenzene Photoswitch
ChemBioChem, Volume 24, Issue 5, March 1, 2023., 2023 When amber means “go”: A perfluorinated azobenzene was synthesized and stapled to free cysteines within a helical peptide by using site‐selective perfluoroarylation chemistry. Illumination experiments proved successful change of the peptide's secondary structure in response to amber light.

Free Vibration Analysis of Bulkhead‐Stiffened Functionally Graded Open Shell Using a Meshless Method
Shock and Vibration, Volume 2022, Issue 1, 2022., 2022 This paper focuses on the free vibration analysis of bulkhead‐stiffened functionally graded open shell (FGOS) by means of the first‐order shear deformation theory (FSDT) and the meshless strong form method. The bulkhead‐stiffened FGOS is decomposed into several segments without bulkhead, and the equations of motion and boundary conditions for each ...

Catalytic and structural properties of ATP‐dependent caprolactamase from Pseudomonas jessenii
Proteins: Structure, Function, and Bioinformatics, Volume 89, Issue 9, Page 1079-1098, September 2021., 2021 Abstract Caprolactamase is the first enzyme in the caprolactam degradation pathway of Pseudomonas jessenii. It is composed of two subunits (CapA and CapB) and sequence‐related to other ATP‐dependent enzymes involved in lactam hydrolysis, like 5‐oxoprolinases and hydantoinases.

Analyzing of thick plates with cutouts using the meshless (EFG) method based on higher order shear deformation theories for solving shear-locking issue [PDF]
Numerical Methods in Civil Engineering, 2021 Although the finite element method (FEM) is a well-established method for modelling the thick plates, in some cases FEM encounters some difficulties such as shear locking and decrease in the accuracy of results caused by stress concentration around the ...
