Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures

Small, EarlyView.
Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).

Analysis of material positioning towards microstructure of the friction stir processed AA1050/AA6082 dissimilar joint

Advances in Industrial and Manufacturing Engineering, 2020
Friction stir processing (FSP) is considered to be the newly developed technique which was derived from the welding technique called friction stir welding (FSW). This technique modifies the microstructure of the material through stirring.

Analysis and Comparison of Friction Stir Welding and Laser Assisted Friction Stir Welding of Aluminum Alloy [PDF]

Materials, 2013
Friction Stir Welding (FSW) is a solid-state joining process; i.e., no melting occurs. The welding process is promoted by the rotation and translation of an axis-symmetric non-consumable tool along the weld centerline. Thus, the FSW process is performed at much lower temperatures than conventional fusion welding, nevertheless it has some disadvantages.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Rolling to control residual stress and distortion in friction stir welds [PDF]

, 2010
Considerable residual stress and distortion can be produced by friction stir welding, impeding industrial implementation. Finite element analysis has been used to develop three innovative rolling methods that reduce residual stress and distortion in ...

Anchorage performance of different punching shear reinforcement elements in cracked concrete

Structural Concrete, EarlyView.
Abstract Extensive research has been conducted on the bond and anchorage behavior of reinforcement elements in concrete. While many experimental studies have focused on uncracked concrete, the anchorage performance in the presence of cracks remains insufficiently understood.

Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, EarlyView.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Optimal workplacement for robotic friction stir welding task [PDF]

, 2013
Robotic manipulators are widely used in industry for welding processes. Inadequate joint stiffness in the manipulators often limits their use for high quality welding operations because of the deformation errors produced during the process.
