2026-07-09 Geometric data for elliptical head with uniform thickness (A=100-1000mm, t=10-130mm) doi:10.57760/sciencedb.42059 en This dataset contains geometric measurement data for elliptical heads with uniform thickness. The inner surface is a standard 2:1 elliptical head (semi-major axis A, semi-minor axis A/2). The outer surface is generated by offsetting the inner surface along the normal direction by thickness t. Total data points: approximately 500. Variables include: A_mm (semi-major axis), t_mm (uniform thickness), E_mm (eccentricity from center axis), theta_deg (angle from short-axis vertex), and L_mm (arc length from short-axis vertex). The data support a study on the applicability of geometric calculation formulas for equal-thickness elliptical heads. elliptical head; geometric calculation; standard ellipse formula; CAXA 王亮 PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
