The ALF-SEM Method

Structural Nail
Modeling Method

ALF-SEM treats the artificial nail not as a decorative surface, but as a load-bearing architectural system. Developed over more than a decade of practice and published in 2025.

"Geometry is not decorative — it is biomechanical."

— Hanna Khalin, ALF-SEM

01
Controlled Geometric Framework

Modeling guided by defined geometric references rather than visual estimation.

02
Biomechanical Load Distribution

Material allocated according to how the finished nail will actually be loaded.

03
Standardized Thickness Zoning

Proximal control zone, apex zone, transition gradient, free-edge zone — each with defined parameters.

04
Apex-Centered Structural Balance

Apex position is a calibrated structural decision, not an aesthetic preference.
