Polymer Classification: Stereospecificity

2.5K
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...

Yield Criteria for Ductile Materials under Plane Stress

210
In designing structural elements and machine parts using ductile materials, it is crucial to ensure that these components withstand applied stresses without yielding. Yielding is initially determined through a tensile test, which evaluates the material's response to uniaxial stress. However, tensile stress is insufficient when components face biaxial or plane stress conditions This condition requires advanced criteria to predict failure.
The Maximum Shearing Stress Criterion, also known as...

Area of Science:

  • Materials Science
  • Mechanical Engineering
  • Additive Manufacturing

Background:

  • Load-bearing applications necessitate understanding the strength of additively manufactured materials.
  • Limited research exists on the shear strength of additively manufactured polymers, despite numerous tensile strength studies.

Purpose of the Study:

  • To propose and validate a new measurement approach for interlayer shear strength.
  • To investigate the shear strength of polyamide 12 (PA12) specimens produced via fused deposition modeling (FDM) and selective laser sintering (SLS).

Main Methods:

  • Developed a novel necking-shaped shear specimen for pure shear strength measurement.
  • Utilized three-dimensional (3D) finite element analysis to support experimental shear strength testing.
  • Conducted fractography analysis to investigate shear failure mechanisms.

Main Results:

  • Fused deposition modeling (FDM) and selective laser sintering (SLS) PA12 specimens exhibited distinct shear failure behaviors.
  • FDM-PA specimens demonstrated over a 32% increase in ultimate shear strength compared to SLS-PA specimens.
  • Interface mechanics principles were applied to analyze differing failure mechanisms.

Conclusions:

  • The developed shear strength measurement approach is effective for additively manufactured polymers.
  • FDM processing results in superior interlayer shear strength in PA12 compared to SLS.
  • Understanding shear failure mechanisms is crucial for optimizing additively manufactured components for structural applications.
