How to Use
- Select physics domain from cat-filter: Mechanics, Kinematics, Dynamics, or Relativity
- Input material properties (density, elastic modulus) and geometric constraints (length, cross-section)
- Define initial conditions: velocity (m/s), acceleration (m/s²), mass (kg), or relativistic parameters (velocity as fraction of c)
- Set boundary conditions and load cases, then execute simulation
- Analyze results: displacement fields, stress distribution, trajectory plots, energy diagrams
Worked Example
Steel cantilever beam (E=200 GPa, L=1.5m, rectangular section 50×100mm) under triangular distributed load (peak 5 kN/m). Simulation yields: maximum deflection δ=8.4mm at free end, maximum bending stress σ=145 MPa at fixed support, strain energy U=31.8 J. For relativistic scenario: electron accelerated to 0.9c shows relativistic mass increase factor γ=2.29, requiring 5.2× classical kinetic energy compared to non-relativistic calculation.
Practical Notes
- Mesh density directly affects accuracy—use 0.05m elements for stress concentrations, 0.2m for bulk regions in finite element analysis
- Material damping coefficient (0.02–0.05 for structural steel) prevents numerical oscillations in impact dynamics
- Relativistic calculations become mandatory above v>0.1c; classical mechanics introduces 0.5% errors at this threshold
- Time-step selection: Δt must satisfy CFL condition (Δt ≤ Δx/v_max) for explicit integration schemes
- Validate against hand calculations using Euler-Bernoulli beam theory or energy methods before production runs
