The past decade has seen exciting progress of science and technology at micro/nanometer scale materials and devices. The progress has stimulated a resurge of research on mechanical behaviors of small-scale solid materials. Although traditional solid mechanics models (such as elastic rod, plate and shell models) have been widely applied to study simple mechanical phenomena of such small-scale materials, they cannot be applied to complex mechanics problems due to new features of surface forces and microstructures at the micro/nano scales. This has raised a major challenge to the solid mechanics community.

在过去的十年里，微/纳米尺度材料和器件的科学和技术取得了令人兴奋的进展。这一进展促进了小尺度固体材料力学行为研究的复苏。虽然传统的固体力学模型（如弹性杆、板、壳模型）已被广泛应用于研究这类小尺度材料的简单力学现象，但由于微/纳米尺度下表面力和微观结构的新特征，它们无法应用于复杂的力学问题。这对固体力学界提出了重大挑战。
