    摘要:

    為了更深入地認(rèn)識(shí)鈦合金鉚釘成型時(shí)鐓頭內(nèi)溫度場(chǎng)的變化及其對(duì)絕熱剪切帶形成的影響，在ABAQUS平臺(tái)上建立了3D有限元模型，綜合考慮了材料的應(yīng)變硬化、應(yīng)變率硬化、熱軟化效應(yīng)及摩擦和結(jié)構(gòu)的非線性。計(jì)算表明：剪切帶內(nèi)應(yīng)變高度集中，溫升高達(dá)500 ℃，高溫區(qū)域與剪切帶基本重合，最高溫度超過了其再結(jié)晶溫度

    Abstract:

    To better understand the temperature field in the upsetting head of a titanium alloy rivet and its influence on the forming of ASBs, a three dimensional FE model was built on the ABAQUS platform, fully taking into consideration the strain hardening, strain rate hardening and thermal softening effect of the rivet material and friction and nonlinear behavior of the structure. Computation results show that ASBs experience a high strain concentration during the process and the high temperature zones coincide with the ASBs basically. It is observed that the temperature rise in the ASBs reaches to 500 oC, which means the highest temperature in the rivet exceeds its recrystallization?temperature
