Development and calibration of a structural simulation method of CF-SMC composite parts processed by compression molding
The need for the reduction in CO2 production in automotive field increasingly leads
manufacturers to consider fiber-reinforced composite materials that are however costly to
processes. Discontinuous fiber composite materials, like CF – SMC, are a competitive
candidate because they are transformed by the high productivity compression molding
technology. On the negative side, their structural complexity introduces high variability in the
mechanical performance that needs to be considered at the design stage. This contribution
describes the development of a structural modeling strategy for parts made of CF-SMC
processed by compression molding. It is based the statistical material model proposed by
Feraboli implemented here in a FEA-based structural analysis procedure. After validation and
calibration of a specific CF-SMC material, the proposed procedure is applied to the simulation
of the structural response of a compression molded part of complex geometry subjected to
know loading condition
Optical Strain Gauge for High Temperature Plastic Deformation Measurement
Nondestructive evaluation techniques for aging components are becoming very important methods for identification of material degradation, life assessment and development of inspection strategies. In this frame a laser system suited for measurement of permanent deformations in power plant pipes has been designed, built-up and in-field tested
