Determining Actual Contact Area for Longitudinal Assembling of Pressure Joints

Key Points

• The aim is to determine how the actual contact area depends on surface roughness and contact pressure across different material combinations.
• Conducted experiments to measure contact area during longitudinal assembly.
• Analyzed the influence of roughness on the volume of voids.
• Investigated the relationship between contact pressure and contact area.
• Established a correlation between surface roughness and the actual contact area.
• Found that increased contact pressure reduces the volume of voids.
• Demonstrated varying effects across different material pairs.
