LEAPS
Multilayer elastic theory with point, line and circular loads, interfaces from bonded to frictionless, and live stress bulbs.
Which units will you work in?
Every input and every result is reported in the system you pick. You can change it later from the toolbar.
Maxima across every evaluated load station. Tension positive.
The engine
Burmister multilayer elastic theory solved in Hankel-transform space, with overflow-proof boundary conditions and near-exact surface responses.
Three idealizations
The same total load as a concentrated force, spread along a line, or spread over a circular imprint, switched in one control, so Saint-Venant is something you watch rather than read about.
Conventions
Tension-positive stresses, z downward, deflection positive down, engineering shear strains, interfaces on a WinJULEA slip value. SI or English display, mm·N·MPa internally.
