Stress and Deformation Behavior of 2D Composite Cellular Actuator Structures of Ceramic Building Blocks and Epoxy Resins

“…Ceramic building blocks were produced using PZT and Al 2 O 3 injection mold according to our invented methods, [24,25,31,32] as shown in Figure 1.…”

“…[12][13][14][15][16][17][18][19] Idealized and periodically arranged cellular solids were analyzed using different analytical and experimental models. [1,2,[12][13][14][15][20][21][22][23][24][25] A novel field of research addresses the modular assembly of cellular ceramic structures from individual macroscopic building blocks into which the corresponding structure is disassembled. These modular units named as building blocks can be individually functionalized and excited.…”

“…These modular units named as building blocks can be individually functionalized and excited. [24,25] Eichhorn et al [24,25] investigated such novel structures through finite element (FE) simulations and determined the strain amplification and stress behavior as a function of geometric parameters such as the slenderness ratio t 2 • g À1 . These periodic cellular structures were parameterized and with the support of algorithms different variants of the geometric structure could be generated.…”

“…These periodic cellular structures were parameterized and with the support of algorithms different variants of the geometric structure could be generated. [24,25] Gohari et al, [26] Ray et al, [27] and Steiger et al [28] used numerical models and FE simulations as ABAQUS to investigate plate-and bar-shaped, dense composite actuator models made consisting of lead zirconate titanate (PZT) fibers in an epoxy resin matrix. FE simulations were compared with various mathematical theories to verify the models.…”

“…The optimization of the structure was performed by parameter variation to generate maximum strain gain under mechanically coupled thermal excitation. Following Eichhorn et al, [24,25] it was assumed for the simulations that the thermal expansion correlates directly with the piezoelectric expansion due to the crystalline material structure. The variations in strain amplification as well as stress DOI: 10.1002/pssb.202100591 2D actuator composite structures are fabricated of lead zirconate titanate (PZT) and Al 2 O 3 building blocks with an epoxy resin matrix.…”
