Beam Stress Loading Types: Direct; Eccentric; Bending & Torsion Calculators

Bending of cantilever beam
Calculates reactions, bending moments, shear forces and deflections of cantilever beams.

Bending of orthotropic plate
Calculates deflections and stresses of simply supported orthotropic rectangular plate under uniformly distributed load applied to rectangular area.

Bending of simply supported beam
Calculates reactions, bending moments, shear forces and deflections of statically determined beams. The result is represented as diagrams of these components of the beam. Calculation is helpful not only for structural engineers, but also for students because all main steps (formulas) of the solution are provided.

Bending of statically indeterminate (continuous) beams
Calculates reactions, bending moments, shear forces and deflections of statically indeterminate (continuous) beams. The result is represented as diagrams of these components of the beam. All main steps (formulas) of the solution are provided.

Buckling of orthotropic plate
Calculates the critical load of simply supported rectangular plate uniformly compressed in two directions.

Curve Fitting
This calculation allows obtaining approximation of data using generalized Pade (rational) functions. The accuracy of approximation can be managed by user changing values of three main parameters: number of coefficients of Pade function; given accuracy, and correlation coefficient of data fitting. We suppose that this calculation will be useful for researchers and engineers looking for good approximation of data with simple formula.

Find reactions for simply-supported beam
Enter values for loads and their positions along the beam, using any consistent units. To eliminate a load, set its magnitude to zero. Refer to the diagram for variable names.

Online Structural Engineering Software | Shock Absorber
Calculates the main characteristics of a novel shock (energy) absorber: load-displacement diagram, maximum stresses and absorption energy for a cycle of loading. The shock absorber contains spring and thin elastic reversing shell of revolution with nonlinear behavior.

Online Structural Engineering Software | Thin Shell by Large Deflections
Calculates the nonlinear load-displacement diagram, maximum stresses by large deflections of the orthotropic clamped spherical thin shell under concentrated force.

Online Structural Engineering Software | Truss
The purpose of this model is calculation of reactions and internal forces of tension or compression in truss members of statically determinate 2D trusses. It is helpful not only for structural engineers, but also for students because all main steps of the solution are provided.
