In aerospace industry, Fatigue Crack Propagation pose a serious threat to the professionals involved in designing mechanical assembly of aircraft structures. these structures crack growth is problem that needs be handled seriously, as human life risk concerned addition economic loss. Growth (FCG) Rate rate at which grows with number cycles subjected constant amplitude loading. FCG curve drawn b...

A methodology for interpreting instrumented sharp indentation with dual sharp indenters with different tip apex angles is presented by recourse to computational modeling within the context of finite element analysis. The forward problem predicts an indentation response from a given set of elasto-plastic properties, whereas the reverse analysis seeks to extract elasto-plastic properties from dep...
