Introduction
Geometric Nonlinearities
Large displacements problems Large strain formulation |
Lesson 1:
Material Nonlinearities
Nonlinear elasticity
Hyperelasticity (Mooney-Rivlin, Ogden) Plasticity (von Mises, isotropic/kinematic/mixed hardening rules) Temperature dependent material properties Visco-elasticity and creep |
|
Lesson 2: Real-World Contact Definition
Contact (Boundary) Nonlinearities
3D nonlinear gap/contact analysis (with or without material nonlinearities). |
Lesson 3: Numerical
Procedures
Solution control techniques (force, displacement, and Arc-Length
controls)
Equilibrium Iterations schemes (Newton-Raphson, modified Newton-Raphson) Termination schemes (convergence and divergence criteria) |
|
Lesson 4: Special Topics
Adaptive automatic stepping algorithm
Prescribed non-zero displacements associated with time curves Deformation dependent loading Analysis stabilization techniques |
Lesson 5:
Viewing the Results

Displacement and stress color filled contour plots Animation of deflected shape, displacement, and stress contour plots X-Y plots for response quantities Isoplanes and sectioning |
ACADEMIX is a training division of EGS India, started in 1996, to impart leading
edge technology to the design and development engineers. Addressing the Fit,
Form and Functional aspects of design, the training provided is intended to address
real-world challenges. Corporates and Individuals are trained in many facets
of Engineering Design. Some of them are:
