Will the virtual work be valid in finite deformation?

"We see from the above that the virtual work statement is precisely the weak form of equilibrium equations and is valid for non-linear as well as linear stress-strain (or stress-strain rate) relations." --- written by O.C. Zienkiewicz etc. at Page 71 of <The Finite Element Method: Its Basis and Fundamentals  Sixth edition>


Here is my question: Will the virtual work still be valid for the case of non-linear strain-displacement relations (finite deformation)?

Asymmetric flexural behavior from bamboo’s functionally graded hierarchical structure: Underlying mechanisms

As one of the most renewable resources on Earth, bamboo has recently attracted increasing interest for its promising applications in sustainable structural purposes. Its superior mechanical properties arising from the unique functionally-graded (FG) hierarchical structure also make bamboo an excellent candidate for bio-mimicking purposes in advanced material design. However, despite its well-documented, impressive mechanical characteristics, the intriguing asymmetry in flexural behavior of bamboo, alongside its underlying mechanisms, has not yet been fully understood.

PhD Robust Optimization Viscoelastic Sandwiches

Visco-elastic structures are widely employed for vibration damping. Nowadays, optimal design of these structures has become commonplace. However, operating conditions introduce variability in their performances. Taking into account this variability in the optimization loop is necessary to obtain optimal robust solutions.

Ionic Cable

This paper demonstrates a new type of interconnects to fulfill the primary function of axons: transmitting electrical signals over long distances and at high speeds. The interconnect, which we call "ionic cable", uses ions to transmit signals, and is built entirely with soft, elastic materials-elastomers and gels. The ionic cable is highly transparent, and remains functioning after being stretched nearly eight times its original length. We describe the design, theory and experiment of the ionic cable.
