The numerical simulation of casting process can calculate casting filling process,
solidification process, and obtain change and coupling information of temperature field …

In this paper, we extend the dynamic spherical cavity expansion model for rate-independent
materials developed by Durban and Masri (Int J Solids Struct 41 (20): 5697–5716, 2004) …

The shape of solder joints formed during the soldering process has a significant impact on
the reliability of electronic products. While various methods have been developed to predict …

Representing the time-dependent plastic behaviour of geomaterials is a critical issue in the
correct application of tunnelling design techniques such as the convergence-confinement …

Despite the definition of failure being almost thoroughly studied in other theories such as
elasto-plasticity, this paper studies the possibility of capturing or defining some limit states in …

Drucker-Prager 屈服函数, 各向同性硬化和Perzyna 黏塑性流动模型. 基于黏弹性蠕变柔度 …

Motivado por diversos processos de manufatura, tais como conformação de metais a frio ou
mesmo manufatura aditiva, este trabalho consiste no desenvolvimento de um código …

In this paper, we extend the dynamic spherical cavity expansion model for rate-independent
materials developed in refs.[1, 2, 3] to viscoplastic media. For that purpose, we describe the …

Estimation of formability is important for sheet metal forming in order to get desired results
with minimum amount of experiments. This can be achieved by having a proper constitutive …
