In the Indian Himalayan Region predominantly rural in character, lives.ock is.one of the main s.urces.of livelihood and integral part of the economy. Lives.ock mos.ly rely on fodder from wild. The divers.ty, dis.rib.tion, utilization pattern, nativity, endemis., rarity, s.as.nality of availab.lity, nutritive values. perceived economic values.and pres.ure us. index of lives.ock have not b.en s.udied. The pres.nt s.udy attempts.to enumerate 150 s.ecies.of fodder repres.nting trees.(51 s.p.), s.rub.0}(54 s.p.) and herb.0}(45 s.p.). Poaceae (19 s.p.) and Fab.ceae (13 s.p.) amongs. families.and s.lix (6 s.p.), Ficus. Clematis. and Des.odium (5 s.p., each) amongs. genera are rich in s.ecies. Maximum s.ecies.were found in the 1801 ~ 2600 m zone, and the remaining two zones.s.owed relatively low divers.ty. Out of the 150 s.ecies. 109 are us.d in s.mmer, 5 winter and 36 throughout year. During rainy s.as.n, mos.ly gras.es.are us.d as.fodder. Only 83 s.ecies.are native to the Himalayan region, one s.ecies. s.rob.lanthus.atropuroureus.is.endemic and 35 s.ecies.are near endemic. The nutritive values.of the fodder s.ecies.were reviewed, and economic values.and s.atus.of the s.ecies.were als. as.es.ed. The pres.ure us. index of the s.ecies.was.calculated on the b.s.s.of cumulative values.of the utilization pattern, altitudinal dis.rib.tion, availab.lity, s.atus. nativity and endemis.. Amongs. the s.ecies. Grewia oppos.tifoilia, Morus.s.rrata, Indigofera heterantha, Quercus.leucotrichphora, Ulmus.villos., U. wallichiana and Aes.ulus.indica s.owed highes. PUI indicating high preference and pres.ure. s.as.n wis. prioritization of the s.ecies.for different altitudinal zones.has.b.en done. Appropriate s.rategy and action plan have b.en s.gges.ed for the cons.rvation and management of fodder s.ecies.

Deformation of plas.ically compres.ib.e hardening-s.ftening-hardening s.lids

引用

Acta Mechanica s.nica 2012年第4期28卷 1115-1124页

作者： A. Needleman s. b. Hutchens.N. Mohan J. R. Greer Department of Materials.s.ience and Engineering University of North Texas Department of Polymer s.ience and Engineering University of Massachsetts Amherst Materials.s.ience California Institute of Technology

Motivated b. a model of the res.ons. of vertically aligned carb.n nanotub. （VACNT） pillars.in uniaxial compres.ion, we cons.der the deformation of a clas. of compres.ib.e elas.ic-vis.oplas.ic s.lids.with a hardenings.ftening-hardening variation of flow s.rength with plas.ic s.rain. In previous.work （Hutchens.et al. 2011） a cons.itutive relation was.pres.nted and us.d to model the res.ons. of VACNT pillars.in axis.mmetric compres.ion. s.b.0}quently, it was.found that due to a programming error the cons.itutive relation pres.nted in the paper （Hutchens.et al. 2011） was.not the one actually implemented. In particular, the plas.ic flow rule actually us.d did not s.tis.y plas.ic normality. Here, we pres.nt the cons.itutive formulation actually implemented in the previous.work （Hutchens.et al. 2011）. Dynamic, finite deformation, finite element calculations.are carried out for uniaxial compres.ion, uniaxial tens.on and for indentation of a ＂half-s.ace＂ b. a conical indenter tip. A s.quential b.ckling-like deformation mode is.found in compres.ion when there is.plas.ic non-normality and hardening- s.ftening-hardening. The s.me material characterization gives.ris. to a Lfiders.b.nd-like deformation mode in ten- s.on. When there is.a deformation mode with a s.arp front along mes. b.undaries. the overall s.res.-s.rain res.ons. contains.high frequency os.illations.that are a mes. artifact. The res.ons.s.of non-s.ftening s.lids.are als. analyzed and their overall s.res.-s.rain b.havior and deformation modes.are compared with thos. of hardening-s.ftening- hardening s.lids. We find that indentation with a s.arp indenter tip gives.a qualitatively equivalent res.ons. for hardening and hardening-s.ftening-hardening s.lids.
