ONE-NODE SQUADRATURE FOR EXPLICIT ISOGEOMETRIC ANALYSIS IN STRUCTURAL DYNAMICS (0623)

Explicit structural dynamics codes used to simulate crash, metal forming and explosions require optimized solution updates to achieve highly efficient calculations of transient processes. To achieve this, linear finite element codes use mass concentration, reduced quadrature and hourglass stabilization. A competitive higher order technology

– with the potential to deliver more efficient simulations – has not yet been realized.

USP (Unique Selling Point)

► Computational costs for evaluating the constitutive routines are reduced by at least a factor of 10. ► Higher order accuracy is maintained, enabling computation on coarser meshes, reducing computational costs by at least a factor of 10. ► Computation modules are perfectly structured for GPUs, further accelerating by at least a factor of 10.

TRL (Technology Readiness Level)

Explicit dynamics calculations are characterized by complex, nonlinear material behavior, which leads to computationally intensive constitutive routines that must be evaluated at each quadrature point in each time step. Our invention is an innovative quadrature technique that achieves for the first time the minimum number of global evaluations while maintaining higher order accuracy. The computational cost of evaluating the constitutive routines is therefore comparable to the linear finite element method.
