Tác động của độ nhám hạt đến cường độ, biến đổi thể tích, năng lượng đàn hồi và năng lượng tiêu hao trong quá trình nén triaxial đồng nhất bán tĩnh sử dụng DEM
Tóm tắt
Một thí nghiệm nén triaxial đồng nhất bán tĩnh trên cát không có độ kết dính dưới áp suất bên không đổi đã được mô phỏng bằng cách sử dụng mô hình DEM ba chiều. Độ nhám hạt được mô phỏng thông qua các cụm đối xứng cấu thành từ các hình cầu cứng để giả lập hình dạng hạt không đều. Tác động của độ nhám hạt đến cường độ cắt, độ giãn nở, năng lượng động học, năng lượng đàn hồi và năng lượng tiêu hao đã được phân tích một cách số liệu. Một số kết quả số liệu đã được so sánh với các kết quả thực nghiệm có sẵn.
