Reports by Q.L. He and Co-Researchers Describe Recent Advances in Mechanical Engineering

【摘要】 2011 JAN 19 - (VerticalNews.com) -- According to recent research published in thernjournal Acta Mechanica, "An energy dissipation rate concept is employed in conjunction withrnthe J-integral to calculate crack growth resistance of elastic-plastic fracture. Different fromrnRice's J-integral, the free energy density is employed in place of the stress working density torndefine an energy-momentum tensor, which yields that the slightly changed J-integral is pathrndependent regardless of incremental plasticity and deformational plasticity."
