Amongst other works, his projects integrating kinetic structures e.g. include 'Ernsting Warehouse and Distribution Centre' (1985) and the 'Planetarium of the Valencia Science Centre' (1991).
This principle allows the reduction of input energy activating spring-back effects through bend-stiffening of the material.
The co-produced cavities for functional integrations of structural and sandwich materials, piping, smart sensing/wiring and mechanically responsive components are chances for the production of multivalent building envelopes.
Furthermore, activation of such smart elements may be optimized through additional introduction of ducts, cuttings, perforations and layering developing composite material characteristics.

This approach, however,
requires sound modeling techniques, analysis tools, engineering judgement and adequate material models for
the explosive, casing and shield materials.

Abstract.
Altering the Mn3+/Mn4+ ratio will affect the FM coupling which in turn affects the electrical conductivity of these types of materials [2].
La0.7Sr0.3MnO3 is one of the candidates for a good CMR material.
As stated by Feng et al., nickel substitution in La0.7Sr0.3Mn1-xNixO3 material decrease the metal-insulator transitions temperature and increases the overall resistivity [11].

Abstract.
In recent years, although many studies have been reported on the growth and characterization of the non-polar AlGaN materials [6, 7], the non-polar AlGaN epi-layers grown on sapphire substrates still suffer from a high density of threading dislocations (TDs) and basal stacking faults (BSFs) owing to the large lattice mismatch between AlGaN epi-layer and the sapphire substrate [8, 9].
is the band gap energy at 0 K. α and β are related constants for the semiconductor material.
Considering the anisotropy of the non-polar material, the strain between the quantum wells and barriers along the (1-100) m-direction and the (0001) c-direction could be respectively defined as:

The properties of the three materials are listed in Table 1.
Similar results were found for other materials and shapes under load.
These results show that landing gear made with the above materials does not exceed the yielding or maximum stress and strain of the material, under different static loads.
Landing gear of different materials and different shapes also exhibit similar results.
The results of the dynamic load test show that landing gear of different materials and shapes have different characteristics.
