The stability of compressive residual stresses and the stability of strain hardening states are seen to have high technical importance. For a laser beam welded AlMgSiCu-alloy, results of applied stress and residual stress relaxation at elevated temperatures 100<T<150°C are presented. These experiments prove the existence of back stresses. The level of these stresses can be estimated to be in th...
Untuk sesuatu rekaan, pembinaan serta ujian jentera-jmtera memproses dan mesin-mesin pengangkutan bahan-bahan biological, sifat-sifat mekanikal bahan-bahan tersebut perlu diketahui terlebeh dahulu. Oleh kerana percubaan-percubaan yang lampau dapat mempastikan bahawa bahan-bahan biological bersifat viscoelastic, perlulah ianya dinyatakan supaya dapat dipastikan tindak balas sifat-sifat tersebut ...
Local magnetic measurements in a highly anisotropic Nd-Ce-Cu-O crystal reveal a sharp onset of an anomalous magnetization peak at a temperature-dependent field Bon. The same field marks a change in the field profiles across the sample, from profiles dominated by geometrical barriers below Bon to Bean-like profiles above it. The temperature dependence of Bon and the flux distribution above and b...
The main load-bearing network in the primary cell wall of most land plants is commonly depicted as a scaffold of cellulose microfibrils tethered by xyloglucans. However, a xyloglucan-deficient mutant (xylosyltransferase1/xylosyltransferase2 [xxt1/xxt2]) was recently developed that was smaller than the wild type but otherwise nearly normal in its development, casting doubt on xyloglucan's role i...
