This chapter discusses the advantages and complexities of ultra high molecular weight polyethylene (UHMWPE) when used as a bearing material for total joint arthroplasty (TJA) and total knee arthroplasty (TKA). The UHMWPE internal structure and its mechanical response depend strongly on a diversity of factors that include radiation crosslinking, fiber reinforcement, and the addition of antioxidants such as Vitam...
Continuous bridge decks constructed with precast beams undergo important stress changes owing to concrete delayed deformations and phased construction. These stress redistributions can be determined through detailed finite-element phased analyses or, alternatively, by employing the effective modulus method (EMM). In this work, the accuracy of the EMM is discussed. Guidance on the quantification of the parameter...
