Plastic Deformations of Members with a Single Plane of Symmetry

Plastic Deformations of Members with a Single Plane of Symmetry

When a structural member undergoes plastic deformation due to bending, it is crucial to understand the position of the neutral axis and the stress distribution. This member, characterized by a single plane of symmetry, exhibits a uniform stress distribution, with negative stress above the neutral axis and positive stress below. Notably, the neutral axis does not align with the centroid of the cross-section. This misalignment is typical in cases where the cross-section is not rectangular or...

Deformations in a Transverse Cross Section

Deformations in a Transverse Cross Section

When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...

Transformation of Plane Strain

Transformation of Plane Strain

When analyzing elongated structures like bars subjected to uniformly distributed loads, it is essential to understand the transformation of plane strain when coordinate axes are rotated. This transformation helps to assess how material deformation characteristics vary with orientation, which is crucial in materials science and structural engineering.
Under plane strain conditions, typical for members where one dimension significantly exceeds the others, deformations and resultant strains are...

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Eccentric Axial Loading in a Plane of Symmetry

Eccentric Axial Loading in a Plane of Symmetry

Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

Fascicle Arrangement in Skeletal Muscles

Fascicle Arrangement in Skeletal Muscles

Fascicles are bundles of muscle fibers in a skeletal muscle. Muscle fascicle arrangement is directly associated with the power and range of motion of various muscles. The configuration of these fascicles can vary, leading to different functional outcomes.
The four primary types of muscle based on fascicle arrangement are:

Area of Science:

Computer Vision
Computational Geometry
Shape Analysis

Background:

Medial representations capture intuitive shape properties like thickness and elongation.
Medial Axis Transform (MAT) is unstable, producing spurious branches requiring pruning.
Existing pruning methods are local or global, with limitations.

Purpose of the Study:

To develop a novel groupwise approach for medial axis skeleton pruning.
To introduce the Groupwise Medial Axis Transform (G-MAT) framework.
To improve the accuracy and robustness of shape skeletonization.

Main Methods:

Proposed a groupwise skeletonization framework (G-MAT).
Developed four groupwise methods for computing branch significance.
Evaluated pruning performance using denoising, classification, and skeleton similarity metrics.

Main Results:

The G-MAT framework provides fuzzy significance measures for skeleton branches.
Superior performance was reported compared to a leading existing method.
Demonstrated effectiveness in denoising, classification, and enhancing within-class skeleton similarity.

Conclusions:

Groupwise analysis offers a more robust approach to medial axis skeleton pruning.
G-MAT effectively addresses MAT instability and improves shape representation.
The framework has significant applications in object retrieval and shape analysis.
