Elastic bending deformation analysis for case of anisotropic corrugated fiberboard box shape (square tube : width L, height h and thickness T=5.54 mm) under uniform compression (-0.10 N⁄mm
2) on upper and lower edges was performed. And characteristic behavior of stress and deflection for its case was discussed.
Absolute maximum normal stress σ
bxmax∗ in the width direction is at plate centers, and maximum normal stress σ
bymax in the height direction, maximum bending principal stress σ
b0max and maximum deflection w
max are at centers of side edges for side plate (L=350, h=300 mm) . Absolute maximum bending shear stress τ
bxymax∗ and maximum bending principal shear stress τ
b0max∗ are plate corners. σ
bxmax∗, σ
bymax, τ
bxymax∗ and w
max increase and decrease with L increase. And σ
bxmax∗ and w
max increase and decrease, and σ
bymax and τ
bxymax∗ increase with h increase. σ
bxmax∗, σ
bymax, τ
bxymax∗ and wmax increase with Ex increase and decrease with E
y increase. σ
bxmax∗ and σ
bymax increase, and τ
bxymax∗ and w
max increase and decrease with ν
xy increase.
