How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

Advanced Materials, Volume 37, Issue 51, December 23, 2025.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

Image‐Based Flaw Identification Using Convolutional Neural Network

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 694-706, December 2025.
ABSTRACT Flaw detection in structures is crucial for ensuring structural integrity and safety across various engineering applications. Traditional nondestructive evaluation (NDE) techniques often face challenges in accurately identifying and characterizing flaws, particularly when dealing with complex geometries and strain fields.

Moving Least‐Squares Aided Finite Element Method: A Powerful Means to Evaluate Distributive and Dispersive Mixing

Polymer Engineering &Science, Volume 65, Issue 12, Page 6750-6761, December 2025.
We present the Moving Least‐Squares Aided Finite Element Method (MLS‐FEM) as a robust approach to evaluate flow fields in polymer mixers. Using a fixed background mesh that is independent of rotor shape and motion, MLS‐FEM captures distributive and dispersive mixing without the need for mesh regeneration.

Stress in Immature Incisor Treated With Regenerative Endodontics or Restored With Bulk‐Fill Resin Composite: A 2D Finite Element Analysis

Australian Endodontic Journal, Volume 51, Issue 3, Page 660-667, December 2025.
ABSTRACT This study investigated the stress distribution on teeth undergoing regenerative endodontic treatment (RET) using two‐dimensional finite element analysis (2D FEA). Five 2D‐FEA models of immature incisors were developed, involving immediately after RET, models after RET varying root length and thickness: 10% increase in root length and root ...

Automating XFEM Modeling Process for Optimal Failure Predictions

Mathematical Problems in Engineering, 2018
The eXtended Finite Element Method (XFEM) is a versatile method for solving crack propagation problems. Meanwhile, XFEM predictions for crack onset and propagation rely on the stress field which tends to converge at a slower rate than that of displacements, making it challenging to capture critical load at crack onset accurately.

Crack Propagation in Tooth Root: A Comparison Between Pulsator Test and Running Gears

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 12, Page 5181-5194, December 2025.
ABSTRACT Tooth root fatigue fracture is a critical gear failure mode in which the tooth root breaks because of the repetition of bending load. The most widely adopted procedure for evaluating root strength is through pulsator testing. However, this test method does not present gears in meshing conditions. When focusing on the limited‐life region of the
