This research work investigated the influence of press molding manufacturing process on mechanical properties, both for thermoplastic and thermosetting fiber reinforced composite materials. The particular geometry case study, called Double Dome, was considered in order to verify behavior Thermoplastic Thermosetting prepreg terms shell thickness variation fibers shear angle evolution during thermoforming process. simulation performed using LS-DYNA® Finite Element Analysis (FEA) code, results...
This paper presents a probabilistic micromechanics-based approach to simulate the influence of scatter sources in composite materials as an alternative deterministic approaches. Focus is given effect microscopic and macroscopic voids, material inhomogeneity induced by manufacturing processes stochastic fibre patterns on mechanical properties continuous glass-fibre reinforced polymer components. Various periodic unit cells neat resin embedded clusters are generated with random distributions...
Abstract An alternative approach to calibrate material models is proposed. The entire displacement field of a specimen measured with DIC system was converted into boundary conditions by the Envyo® mapping software. These were imposed on all nodes in corresponding LS-DYNA® simulation model. In this way digital twin geometry and experimental kinematics obtained. Considering local stress equilibrium over global force integrated many hypothetical cross sections, LS-OPT® used iteratively...
Failure and deformation behavior of veneer laminates ring porous wood species vary with the individual arrangement early- latewood zones over a sheet. Therefore, method is presented, where local failure damage modes are considered for finite element models respect to forming simulations, during development process automotive interior trim parts. Within mapping tool Envyo, routine has been realized discretization from ash surfaces meshes. The performs following steps: reading grayscale image...
We present a modified strain gradient theory of elasticity for linear isotropic materials in order to account the so-called size effect. Additional material length scale parameters are introduced and problem static beam bending is analyzed. A numerical solution derived by means finite element approach. global C1-continuous displacement field applied solutions because higher-order energy density additionally depends on second gradients displacements. So-called Hermite elements used that allow...
Since March 2011, car manufacturers have to consider the newly released Federal Motor Vehicle Safety Standard 226 Ejection Mitigation (FMVSS 226) during vehicle development and for final testing prior release. This safety standard shall prevent occupants from being ejected through vehicle’s side windows made out of laminated glass, especially rollover or side-impact accidents. For evaluation, initially, damaged glass panes are loaded with a head impactor different velocities at positions. In...
