Unsymmetric Loading of Thin-Walled Members: Problem Solving01:07

Unsymmetric Loading of Thin-Walled Members: Problem Solving

467
The shear center of a channel section with uniform thickness, height, and width, is determined by computing the shear force in the member and calculating the moments of inertia of the sections.
To compute the shear forces, find the shear flow at a specific distance from the endpoint using the vertical shear and the moment of inertia values. The total shear force on the flange is calculated by integrating the shear flow from one end of the flange to the other.
Next, calculate the moments of...

Unsymmetric Loading of Thin-Walled Members

Thin-walled members with non-symmetrical cross-sections are vital to engineering structures, offering material efficiency and structural integrity. However, unsymmetrical loading on these members leads to complex stress distributions, resulting in simultaneous bending and twisting can cause deformation or structural failure. The interaction between bending and twisting requires detailed analysis to ensure structural resilience.
The concept of the shear center is crucial in countering the...

Thin-Walled Hollow Shafts

514
In analyzing a thin-walled hollow shaft subjected to torsional loading, a segment with width dx is isolated for examination. Despite its equilibrium state, this segment faces torsional shearing forces at its ends. These forces are quantitatively described by the product of the longitudinal shearing stress on the segment's minor surface and the area of this surface, leading to the concept of shear flow. This shear flow is consistent throughout the structure, indicating a uniform distribution of...

Area of Science:

  • Materials Science
  • Mechanical Engineering
  • Additive Manufacturing

Background:

  • Continuous fiber-reinforced thermoplastic composites (CFRTPCs) are valuable for thin-walled cellular structures.
  • Additive manufacturing (AM) offers efficient fabrication but faces challenges with filament cutting and path-induced defects.

Purpose of the Study:

  • To develop a novel path planning method for AM of CFRTPCs.
  • To address issues of filament jumping, twisting, folding, and breaking during printing.

Main Methods:

  • A Euler graph-based path planning approach was proposed.
  • Non-Eulerian graphs were converted to Eulerian graphs using doubled edges.
  • An optimized Hierholzer's algorithm with pseudo-intersections generated continuous, non-crossing paths, minimizing sharp turns.

Main Results:

  • The optimized Hierholzer's algorithm significantly reduced the average turning angle by up to 20.88%.
  • The number of turns ≤ 120° increased by up to 26.67%, indicating smoother paths.
  • Generated paths were successfully validated using custom robot-assisted AM equipment.

Conclusions:

  • The proposed Euler graph-based path planning method effectively improves the AM process for CFRTPCs.
  • This approach enhances the quality and mechanical integrity of AM parts by avoiding critical printing defects.
  • The study demonstrates a viable solution for defect-free additive manufacturing of complex composite structures.
