damage and fracture

基本解釋

Second, the damage and fracture mechanism was numerically simulated by wave mechanics under the experimental condition.
然后，利用波動(dòng)力學(xué)理論，對(duì)激波在實(shí)驗(yàn)條件下對(duì)水泥試樣的損傷破壞進(jìn)行了數(shù)值模擬。
But the damage and fracture of rock is closely related to each other. And the relationship between strength criterion parameters of rock and fracture toughness of fracture theory is particular.
然而，巖石的破壞和斷裂是緊密相聯(lián)的，巖石強(qiáng)度準(zhǔn)則的材料參數(shù)和斷裂理論的斷裂韌度存在特定的方程關(guān)系。
First, the phenomenon of the rock damage and fracture by shock wave of exploding in fractures was simulated through the experiment of exploding on the surface of the cement sample in deep water.
首先，在水中利用爆炸產(chǎn)生的爆炸沖擊波對(duì)水泥試樣進(jìn)行損傷破壞，模擬“層內(nèi)爆炸”采油技術(shù)中激波使巖石損傷開(kāi)裂的現(xiàn)象；然后，利用波動(dòng)力學(xué)理論，對(duì)激波在實(shí)驗(yàn)條件下對(duì)水泥試樣的損傷破壞進(jìn)行了數(shù)值模擬。

損傷斷裂
Therefore, when the effect of the stress state on the damage and fracture behavior of materials is analyzed and the mechanical model is established, not only the effect of stress triaxiality should be considered, but also the principal stress ratio.
因此在分析應(yīng)力狀態(tài)對(duì)材料的損傷斷裂行為的影響及建立相應(yīng)的力學(xué)模型時(shí)，不僅要考慮三向應(yīng)力度σ_m／σ_(?) ，而且要考慮不同主應(yīng)力比σ_2／σ_1的影響。

損傷破壞
Based on the experiments of exploding on the surface of the cement sample,the phenomenon of the rock damage and fracture by shock waves in exploding was simulated.
通過(guò)水中爆炸波對(duì)水泥試樣的損傷破壞實(shí)驗(yàn)來(lái)模擬水力裂縫層內(nèi)爆炸采油中激波使巖石損傷開(kāi)裂的現(xiàn)象。
