Mae modelu solidau aml-raddfa yn faes o ddiddordeb cynyddol yn y gymuned mecaneg gymhwysol a chyfrifiannol. Gall cysyniadau aml-raddfa ganiatáu datblygu modelau newydd i ddisgrifio ymddygiad cyfansoddol solidau drwy gynnwys gwybodaeth ar ddwy neu fwy o raddfeydd ffisegol. Mae'r gwaith o ddatblygu modelau o'r math hwn, yn enwedig gyda'r defnydd o ddulliau homogeneiddio cyfrifiannol yn seiliedig ar weithdrefnau Elfen Feidraidd, ar y gweill ar hyn bryd.

Un defnydd o ddiddordeb arbennig yw modelu ac efelychu meinweoedd biolegol yn gyffredinol. Mae deunyddiau o'r fath yn gyffredinol yn meddu ar ficrostrwythurau cymhleth sy'n arwain at ymddygiad macrosgopig cymhleth. Mae dulliau aml-raddfa’n cael eu defnyddio ar hyn o bryd yn y cyd-destun hwn wrth fodelu ymateb cyfansoddol rhydwelïau dynol. Mae defnydd pellach o fethodolegau aml-raddfa ar waith ar hyn o bryd yng nghyd-destun modelu metelau amlgrisialog yn ogystal â phroblemau dargludiad gwres yn gyffredinol. Ymhlith y cyfeiriadau ymchwil newydd diweddar yn y maes hwn mae rhagfynegi sensitifrwydd deunyddiau macrosgopig i newidiadau microstrwythurol topolegol, a gyfrifir drwy'r cysyniad deilliadol topolegol fel y'i gelwir. Bydd gweithdrefnau o'r fath yn arwain yn y dyfodol agos at dechnegau newydd ar gyfer optimeiddio microstrwythurol.

Bydd technegau cyfrifiannol aml-raddfa yn arwain at dasgau aruthrol o safbwynt cyfrifiannol. Felly, mae angen optimeiddio effeithlonrwydd cyffredinol y fframwaith aml-raddfa er mwyn gallu ei ddefnyddio wrth ateb problemau ymarferol. Yn y cyd-destun hwn, mae technegau cyfrifiannol sy'n deillio o arbenigedd y grŵp ymchwil hwn wrthi'n cael eu datblygu, a hyd yma maen nhw wedi arwain at ostyngiadau sylweddol mewn amser cyfrifiadura. Rhagwelir datblygiadau pellach yn y dyfodol agos.

EG-3067 Finite Elements for Civil Engineers

This module provides an introduction to the Finite Element Method of analysis. The material delivered in this module is of particular relevance to civil engineers, with focus on the analysis of structural mechanics and groundwater flow problems. Both theory and its application are covered, including elements of Matlab programming in this context and the use of commercial finite element software of widespread use in industry.
EG-M25 Advanced Structural Analysis

The module develops theory and associated solution techniques relevant to structural problems related to plates, shells and solid applications. The basic theoretical concepts are firstly introduced and the underlying governing equations then developed. The first topic considered is the elastic theory of plate bending, which is of fundamental importance in the design and analysis of a large class of engineering structures. This is followed by the limit analysis of plate structures, which is of prominence in reinforced concrete design. A central aspect of the course is the treatment of the membrane analysis of shell structures. Most shell structures operate by their resistance to membrane action, rather than bending, and the course develops solution procedures for a range of practical shell structure applications encountered in both civil and mechanical engineering environments. The course concludes by developing solution strategies for structures subjected to torsion, with particular emphasis placed on the analysis of thin walled structures, such as those encountered in bridge deck construction and aerospace applications.
