衡裂縫 的英文怎麼說
中文拼音 [hénglièféng]
衡裂縫
英文
edge crack-
Thereafter, the fractal dimension value of cracks distribution was presented as an effective index to appraise the corrosion level. relations between fractal dimension and rebar corrosion ratio, concrete deterioration factor and strength of the member were studied respectively. fractal nn model was also built up to predict the ultimate load bearing capacity of crc members obtained from the field corroded structures, good results are achieved, which could provide an applicable method to evaluate the durability of crc members
揭示出受腐蝕鋼筋混凝土構件在荷載作用下表面裂縫分佈服從統計意義上的分形，並對其進行了分形描述；提出以裂縫分形維數作為受腐蝕程度的有效衡量指標，首次實現了構件受腐蝕程度的定量描述；建立了裂縫分形維數與鋼筋銹蝕率、混凝土劣化系數、構件承載力之間的定量關系，並建立了分形神經網路模型對實際受腐蝕鋼筋混凝土構件進行了極限承載力的預測，取得了較好的預測效果。For the high pressure phase equilibrium system composed of co2, h2o, cacl2, etc., co2 is treated as super critical fluid truly, the volume of which is estimated by bwr state equation suitable for super critical fluid
考慮了酸液溶蝕的碳酸鹽以及酸巖反應生成的二氧化碳對人工裂縫體積的影響，針對裂縫內由二氧化碳、水、氯化鈣等物質組成的高壓相平衡體系，將二氧化碳真實地處理為超臨界狀態，其體積由適用於超臨界流體的bwr狀態方程求解。( 5 ) aiming at irregularity of a real fracture surface or a real crack profile, applying griffith ' s criterion and fractal geometry, the real asymptotic expression at the crack tip is developed, and it is discovered that the fractality of the crack reduces the stress singularity at the crack tip
（ 5 ）針對實際斷裂面或裂縫的不規則性，利用griffith能量平衡原理及分形幾何，推導了裂縫尖端實際應力場和位移場的表達式，研究發現，裂縫的分形性減小了裂縫尖端應力的奇異性。The change of moisture distribution is concentrated on the surface layer concrete, which is very thin. however, the change inside the concrete is very slight. this unbalanced development of moisture distribution causes large shrinkage stress in the layer concrete and then leads to crack
混凝土濕度變化主要集中於較薄的表層混凝土內，內部濕度場變化極微，這種濕度發展變化的不均衡使得表層混凝土內產生較大的收縮應力，將直接導致裂縫的產生。Furthermore, obvious linear correlations between the fractal dimension characteristic quantities of surface - crack distribution and the structural physical parameters are revealed under different load spaces, respectively
揭示表面裂縫的分形維特徵量與結構物性參數之間存在明顯的線性相關關系，表明分形維特徵量可以作為衡量結構損傷程度的分形特徵因子。分享友人
