The spontaneous strain in the LC solid beam typically involves both axial normal strain and transverse shear strain. Therefore, we incorporate von Kármán geometric nonlinearity into an LC solid beam model that includes the effects of the spontaneous transverse shear strain to derive the governing equation and relevant bending solution. The results demonstrate that the bistability arises from the compressive axial force within the beam, which is generated by the constraint on its spontaneous elongation. When the beam exhibits bistability, the two stable bending states are oppositely directed, and the transitions between them can be achieved by applying a reversed transverse mechanical load that causes snap-through buckling. Furthermore, the critical conditions for the beam to exhibit the spontaneous bistability and to undergo the mechanical snap-through buckling are obtained through several distinct approaches.

A closed-form expression for the stress intensity factor is derived in the Laplace domain and numerically inverted to the time domain. The method is applied to both impermeable and permeable cracks under constant remote stress, and the instantaneous fracture energy is determined from the stress intensity factor. To validate the semi-analytical findings, a finite element model incorporating cohesive zone elements is developed, and the J-integral is used to compute the instantaneous fracture energy. Results indicate that fluid drainage leads to time-dependent increases in the stress intensity factor and fracture energy, influenced by changes in the effective Poisson's ratio and medium thickness.

This behavior suggests a transition in the dominant deformation mechanism from intergranular grain boundary (GB) deformation to intragranular activities.

Both GNC and HNC models exhibit a combination of intragranular defect multiplications (involving dislocation slip, stacking fault (SF), and twin boundary (TB) expansion) and intergranular GB movement during the plastic deformation, resulting in shear strain homogenization, especially at the GBs. Consequently, the pronounced strain delocalization caused by grain structure inhomogeneity promotes cooperative deformation between GBs and grain interiors, effectively hindering void nucleation and expansion.
