Max$/$min Principal Stress Values per Slab:

MAX: $2\mathrm{.}05184$MPa

X: $3147\mathrm{.}35$mm

Y: $-119\mathrm{.}997$mm

Z: $-99\mathrm{.}99$mm

MIN: $-2\mathrm{.}15657$MPa

X: $1452\mathrm{.}65$mm

Y: $-119\mathrm{.}997$mm

Z: $-0\mathrm{.}01$mm

and stress levels of slab goten fromEverFe software are :$-0\mathrm{.}135$ MPa, $0\mathrm{.}412$ MPa, $0\mathrm{.}958$ MPa, $1\mathrm{.}51$ MPa, $2\mathrm{.}05$ MPa.

solve this problem: slab thickness is $10$cm$,$ if the thickness of the slab increases by $50\%,100\%,150\%,$ and $200\%,$ determine the maximum principal stresses. Afterward, plot charts demonstrating the effect of thickness variations on pavement critical stress responses.
