Analyzing thick and thin domains is quick and easy with StressCheck®’s Modal & Buckling Solver module. In most cases only one element is needed through a part’s thickness for a reliable solution. The computed natural frequencies and buckling load factors exhibit superconvergence. Pre-stress conditions can be easily handled.
Modal & Buckling Solver
This is accomplished with hierarchic modeling and our unique element formulation.
The Modal & Buckling Solver provides a solver and post-processing functionalities for modal analysis and bifurcation (eigenvalue) buckling. Modal and buckling analyses can be performed for both 2D planar problems (plates and beam elements) and 3D problems (shell, extrude and solid elements).
Key Features and Advantages
Modal analysis supports computation of natural frequencies and their associated mode shapes.
- Mass density may be defined as a constant or as a formula
- Mode shapes can be constrained or unconstrained, in which the first six shapes are rigid body modes
- Can specify a pre-stress for 3D problems to account for initial stress conditions
Buckling analysis supports computation of buckling load factors and their associated buckling mode shapes. Both standard and pre-load buckling options are incorporated.
- Standard buckling provides a buckling load factor for a given loading condition
- Pre-load buckling takes into account an additional fixed set of loads (for example, residual stresses) when reporting the buckling factor for applied loads
- StressCheck®‘s high-order elements minimize detrimental locking effects on the eigenvalue solution and promote proper simulation of mode shapes
- The element formulation permits rapid transitions from thin to thick domains
- In many cases only one element is needed through a part thickness
- Convergence information for natural frequencies and buckling load factors is reported
- No limit on number of eigenvalues to be computed
- StressCheck® Handbook simplifies boundary condition influence on buckling load factor and mode shapes by allowing users to switch between support types
Recent News & Events
As companies move to digital product development, simulation plays an increasingly important role in supplying information to support product design decisions. Simulation & Analysis (S&A) Governance is a key strategy to manage simulation for maximum effectiveness over the full product lifecycle. Dr. Keith Meintjes, Practice Manager, Simulation and Analysis at CIMdata states “S&A must be recognized as a strategic capability that companies should develop and foster. This extends from the executive suite where the policy is set and supported, through product and manufacturing managers who are the customers for S&A, to simulation practitioners, who are responsible to deliver simulation on time and with quality.” Formal efforts to improve organizational awareness and to improve technical capability need to be put in place to support this vision
