Interactive engineering calculation and visualization tools.
Interactive visualization of two-dimensional plane-stress transformation, Mohr circle, hydrostatic/deviatoric decomposition, and Tresca/von Mises representations.
Open toolInteractive visualization of a preloaded bolted joint under external tensile load, including bolt and joint stiffness, preload, load sharing, and joint separation.
Open toolInteractive tolerance-stack simulation for a Part 1 + Part 2 assembly — Normal or Linear distributions, a shared manufacturing process capability, and a randomized pairing simulation compared against Worst-case and RSS-predicted spread.
Open toolReaction forces for a rigid body under arbitrary applied forces, moments, and equivalent static inertia loads — xyz, single-, double-, or triple-direction reactions, with a built-in equilibrium crosscheck.
Open toolWorst-case shoulder-bolt fit for parts lowered onto locating pins once and never re-aligned — a dense server-side search of every translation/rotation combination the datum-feature play allows, charged against each hole independently.
