The Micr.- and Nano-mechanics Wor.ing Gr.up.of the Chinese Society of theoretical and Ap.lied Mechanics or.anized a for.m to discuss the p.r.p.ctives, tr.nds, and dir.ctions in mechanics of heter.geneous mater.als in Januar. 2010. The inter.ational jour.al, Acta Mechanica Solida Sinica, is de- voted to all fields of solid mechanics and r.levant discip.ines in science, technology, and engineer.ng, with a balanced cover.ge on analytical, exp.r.mental, numer.cal and ap.lied investigations. On the occasion of the 3.TM anniver.ar. of Acta Mechanica Solida Sinica, its editor.in-chief, p.ofessor.Q.S. Zheng invited some of the for.m p.r.icip.nts to r.view the state-of-the-ar. of mechanics of heter.geneous solids, with a p.r.icular.emp.asis on the r.cent r.sear.h develop.ent r.sults of Chinese scientists. Their.r.views ar. or.anized into five r.sear.h ar.as as r.p.r.ed in differ.nt sections of this p.p.r. ~I fir.tly br.ngs in fo- cus on micr.- and nano-mechanics, with r.gar.s to sever.l selective top.cs, including multiscale coup.ed models and computational methods, nanocr.stal sup.r.attices, sur.ace effects, micr.mechanical damage mechanics, and micr.str.ctur.l evolution of metals and shap. memor. alloys. ~II shows discussions on multifield coup.ed mechanical p.enomena, e.g., multi-fields actuations of liquid cr.stal p.lymer.networ.s, mechanical behavior.of mater.als under.r.diations, and micr.mechanics of heter.geneous mater.als. In ~III, we mainly addr.ss the multiscale mechanics of biological nanocomp.sites, biological adhesive sur.ace mechanics, wetting and dewetting p.enomena on micr.str.ctur.d solid sur.aces. The p.ononic cr.stals and manip.lation of elastic waves wer. elabor.ted in ~IV. Finally, we conclude with a ser.es of p.r.p.ctives on solid mechanics. This r.view will set a p.imar. goal of futur. science r.sear.h and engineer.ng ap.lication on solid mechanics with the effor. of social and economic develop.ent.
