We're continuing to make progress on our customer's most challenging additive manufacturing simulation problems.
At Coreform, we've been developing the capabilities in our isogeometric analysis solver, Coreform Flex, to solve our customer's most challenging additive manufacturing simulation problems. Pads and cushions play a vital role in complex assemblies, including cushioning critical components from mechanical shocks. Additively manufactured (via the direct ink write (DIW) method) pads are a novel approach that allows engineers to tailor the various properties of pads, and reliably manufacture them, in ways unobtainable with traditional manufacturing technologies (e.g., cellular silicone). Even though their shapes might appear simple, it's challenging to perform finite element simulations due to being surprisingly difficulty to hex-mesh and the inherent complexities due to (nearly) incompressible large-deformation elasticity and (frictional) contact. In a previous post, we showed you a single-stack model that we were able to solve and now we wanted to show you our progress on even larger pads. Both examples here are solved with our implicit dynamics solver, using a backward-Euler time integration scheme to recover a quasistatic solution, as well as frictional contact. And, of course, using our fully-automatic meshing approach based on our IGA technologies. #fea #manufacturing #engineering #simulation #cad #cae
