Estimate elastic local buckling stress and thickness sensitivity for a thin rectangular plate.
Critical stress
71.79 MPa
long simply supported plate in longitudinal compression
Width / thickness
60.00
t / b = 0.0167
Critical line load
143.57 N/mm
143.6 kN/m
Compression excites the first local mode; stiffness rises with the square of thickness over width.
71.8 MPa critical
Hover or tap the compression arrows, buckled plate, or curve marker.
coefficient
4.00
long simply supported plate in longitudinal compression
slenderness
60.0
width divided by thickness
plate rigidity
52.37 N m
Kirchhoff plate rigidity D
line load
143.6 N/mm
sigma cr times thickness
