The behavior of solids under forces is called structural mechanics — the fundamental physics behind all machines, objects (cars, rocket ships, toys), buildings, bridges, and so forth.
We build models which involve complex linear and nonlinear
structural mechanics such as hyper-elasticity, large deformation
plasticity, vibrations analysis, fluid-structure interaction,
surface roughness models, ergonomics, rigid body interactions, etc.
FORCE BALANCE SOLVER. Solves specific problems involving linear elastic, non-linear elastic and rigid parts and fluid pressure. Load-deformation curves of each individual body are calculated separately. The force balance solver finds the final resting position in which the entire system will settle.
SHEPHERD ALGORITHM. We created a new algorithm to approximate multi-body interactions, with one elastic and multiple rigid bodies. As the rigid bodies move, the shepherd algorithm quickly creates a feasible solution which is heuristically close to the final solution. Mechanical simulations involving multi-body contact have shown vast speedup using this technique.
FEM WIRE SIMULATOR. A finite element simulator of metallic wire parts. Was commissioned as a validating simulator for a large simulation platform.
