研究了瞬态波在非均匀损伤混凝土介质中的传播,将连续非均匀损伤混凝土介质进行分层均匀损伤的近似处理,利用波谱系数传递矩阵和信号处理手段,计算了3种典型损伤模型对近似脉冲输入信号的时域响应.计算结果表明,由于损伤的存在,将导致响应波的波幅增大,波形畸变,损伤越大,这种增大和畸变的影响程度越明显.
Transient wave propagation in inhomogeneous damaged concrete media was investigated.The continuous inhomogeneous damaged concrete media was approximately treated as stratiform homogeneous damage.Using spectra transfer-matrix and signal processing,impulse
