Structural Mechanics

The beam calculator allows for the analysis of stresses and deflections in straight beams.

The 2D Finite Element Analysis (FEA) calculator can be used to analyze any structure that can be modeled with 2D beams.

The bolted joint calculator allows for stress analysis of a bolted joint, accounting for preload, applied axial load, and applied shear load.

The bolt pattern calculator allows for applied forces to be distributed over bolts in a pattern.

The lug calculator allows for analysis of lifting lugs under axial, transverse, or oblique loading.

The column buckling calculator allows for buckling analysis of long and intermediate-length columns loaded in compression.

The stress-strain curve calculator allows for the calculation of the engineering stress-strain curve of a material.

The Mohr's circle calculator provides an intuitive way of visualizing the state of stress at a point in a loaded material.

The stress concentration calculator provides a set of interactive plots for common stress concentration factors.

Failure Mechanisms

The fracture mechanics calculator allows for fracture analysis of a cracked part.

The fatigue crack growth calculator allows for fatigue crack growth analysis of a cracked part.

Math

The unit conversion calculator allows for conversion between various units, with a focus on engineering units.

Systems Engineering

The trade study calculator provides a systematic method for making a decision among competing alternatives.
