A statistics based numerical investigation on the prediction of elasto-plastic behavior of WC–Co hard metal

On the Statistical Determination of Yield Strength, Ultimate Strength, and Endurance Limit of a Particle Reinforced Metal Matrix Composite (PRMMC)

“…Both plane stress and plane strain models are investigated. It should be noted that in previous studies plane strain models are observed to give more accurate prediction on the elasto-plastic behavior of given composite in small strain regime [8,34]. To check the error caused by finite element type, the current study considers also a special typed 3D model which consists of a thin layered wedge elements obtained by extracting the 2D model in the 3rd direction for 1 µm.…”

“…In [8] it has been shown that the discrepancy between plane stress and plane strain models becomes more obvious when global plasticity accumulates. Also, once global plasticity has reached a critical level, the mechanical behavior reflected by these two model variances are fundamentally different.…”

“…The average grain size is d WC = 2.35 µm . To convert these SEM images to the corresponding FE models an automatic technique developed in [8] is employed. This technique is capable of generating a triangular element based adaptive finite element mesh.…”

“…The technique developed in a previous study [8] is applied in order to overcome the aforementioned main obstacles. Using a series of scanning electron microscope (SEM) images obtained from the material finite element (FE) models are built.…”

Numerical analysis of elastic and elastoplastic behavior of interpenetrating phase composites

“…Previous work on this subject can be broadly classified into three categories, namely theoretical methods [7][8][9], experimental measurements [10,11] and computational simulations [12][13][14][15][16][17][18][19][20][21][22]. Because of the complex microstructure of the IPCs, an analytical method can hardly estimate the mechanical properties precisely.…”
