Further, for complex loading scenarios it is impossible to develop an analytical model.
For complex loading conditions, the behavior of the structural materials is determined by damage evolution, strain rate and temperature.
These predictions are not only insufficiently reliable for complex loading of multidirectional composites, but even for longitudinal tensile failure of unidirectional (UD) composites.
It is found that for complex load histories the yield surfaces are not only shifted but may also change their shape and size considerably.
In order to understand the material's response for complex loading situations the often used J2-plasticity model is inadequate, instead dedicated constitutive models are required.
The ability of ductile damage models to predict both void growth with shape change and void rotation is thus crucial for complex loading applications.
A 3D beam element is used with dimensions of (0.1 m × 1 m × 0.1 m) to test whether the developed 3D elastic numerical model is capable of predicting the stresses profile for complex loading schemes.
Simulations run with FE analysis for complex loading conditions require precise experimental investigation into the modelled material in order to obtain fundamental geometric and material parameters (Bobel et al. 2015).
This paper presents experimental results showing the piezoresistive effect for these complex loads.
Novel lumped dual-frequency impedance transformers (DFITs) for arbitrary frequency dependent complex loads (FDCLs) are synthesized using the concepts of capacitive and inductive inverters.
