“…The proposal to modify the GFRP vessels in their construction [7] by inserting viscoelastic layers is to protect them from the destructive action of slamming and prolong their useful life by decreasing the maintenance and repair times. In fig.…”

“…However, when inserting the viscoelastic layers, the propagation of the impact is damped between the layers, decreasing the damage to the polymeric matrix. The impact is converted into damage energy, and it is transformed into energy absorbed by the viscoelastic material [7].…”

“…The comparison of the results between modified and unmodified panels is capable of evaluating the level of damage and it can be observed how the damage energy is returned affecting to a lesser degree at the micro structural level. It is proven that the proposed modification is the future of shipbuilding in GFRP, and it is the new vision for which the designers of composite structures must walk [7] - [8].…”

The planning hull, are types of boats very used in our days, and require special maintenance and repair. It is proposed the insertion of a viscoelastic layer inside the laminated panels of the ships built with GFRP, to protect them from the impacts of slamming. Unmodified and modified laminate panels were manufactured to perform result comparisons. With the reproduction of the phenomenon of fatigue in the laboratory, testing them in the impact machine, the use of strain gauges and by characterization with fluorescent penetrating inks to observe the evolution of micro cracks. It is verified that the proposed modification is the future of shipbuilding of this type of vessel.

“…Each iteration of this algorithm requires solving the linear elasticity on two meshes, each in O ( n 2 ) asymptotic time with n being proportional to the number of finite elements. Previous experiments show that usually a few initial steps of the finite element algorithm focus on reproducing the material structure with the computational mesh, regardless of the boundary problem solved. This observation leads to the question, whether these iterations could be replaced with a less expensive pre‐processing.…”

An improvement to the workflow used in modeling boundary‐value problems in complex materials, which allows for reducing computational time by the factor of 5 while maintaining comparable quality of the solution is proposed in this paper. After formulating the main goals of the paper, a review of the state‐of‐the‐art techniques used for generating a digital material representation is presented. This is followed by a description of the procedure for solving boundary‐value problems and finding a representation of a given microstructure in a desired functional base. Finally, we showcase how to combine these techniques to obtain mentioned significant calculation speedup. Developed approach is validated during investigation of a selected case study, which is modeling of a linear elastic deformation of a dual phase ferritic–martensitic steel under thermal loading conditions.

“…A combination of experiments [1], analytical modeling [4], and numerical modeling techniques through finite element method with adaptive mesh refinement [5,6] have been used to study various properties of piezoelectric composites. On the basis of the analytical modeling approach, parallel or series micromechanical models, various Homogenization techniques and Esheby's technique for ellipsoidal inclusions have been used.…”

Piezoelectric composite materials with a polymer matrix are important for underwater acoustic and biomedical imaging applications. The dependence of electromechanical properties of piezoelectric composite on constituent material characteristics and shape of piezoelectric inclusions is a central problem that provides the opportunity to tailor the performance of piezoelectric composites according to design needs. A numerical model has been developed to investigate the electromechanical properties of 1-3 piezoelectric composites with a passive and active polymer matrix. Maxwell Homogenization method is employed to homogenize the solution domain. It is demonstrated that the use of PVDF as an active polymer matrix has a significant influence on piezoelectric charge coefficient d31, hydrostatic coefficient dh, voltage coefficient gh, and hydrophone figure of merit ghdh when compared to the passive Araldite-D polymer matrix. Overall, a 5 to 30% volume fraction of PZT-7A fiber inclusions in an active polymer matrix is the optimum ratio that has a significant effect on piezoelectric properties. The accuracy and effectiveness of homogenized material constants were verified by comparing the derived composite properties with experimental work published elsewhere. These results provide much needed intuitiveness in the development of piezoelectric polymer composite with better performance for transducer applications.
